Moin,
this one is so complex, I don't know how to file a bug. I'll try to explain
it here (hope I won't forget half the things.) First, that's what the bug
wizard says about my system:
Version: 1.5 (using KDE 3.1.0)
Installed from: SuSE
Compiler: gcc version 2.95.3 20010315 (SuSE)
OS: Linux (i686) release 2.4.18
Ok, let's start: I found a pretty reliable way to crash KMail. Maybe two.
They sound complicated but are pretty easy to discover in real world usage:
I've got a folder "KMail" and "KMail/Bugs" with the corresponding filters
and I just moved it below a new folder "KDE".
I. The first one is about moving folders.
1. Disable "Settings->Configure->Folders->Warn before expiring" and enable
both "...->On Exit...->Compact all folders" and "...->On Exit...->Expire
old messages".
2. Create a folder /test under your Local Folders
3. Create a folder /test/foo
4. Create a folder /test/foo/bar
5. Create a folder /test/baz
6. Select "Properties..." of foo and change "Belongs to" to "baz". You now
have /test/baz/foo/bar.
7. Exit KMail
What happens now:
1. The PassivePopup "Compacting folders" appears
2. Folders are compatced till 100%
3. The PassivePopup disappears
4. KMail crashes (backtrace "kmail.1.bt" attached)
II. The second one is about filters not being updated. It seems like KMail
recognizes moved folders in filters only if you went to "Settings->
Configure Filters..." and select the filter in question, right?
1. Create again the hirarchy /test/foo/bar
2. Go to "Settings->Configure Filters..."
3. Create a dummy filter like this:
"From" "doesn't contain" "@" => "move to folder" "/test/foo/bar"
4. Create another filter:
"To" "doesn't contain" "@" => "move to folder" "/test/foo"
Make sure that this filter is *above* the previous
5. Press OK. Now you should have this in your kmailrc:
| [Filter #0]
| StopProcessingHere=true
| action-args-0=.test.directory/foo
| action-name-0=transfer
| actions=1
| apply-on=check-mail,manual-filtering
| contentsA=@
| fieldA=To
| funcA=contains-not
| name=<To>:@
| operator=and
| rules=1
|
| [Filter #1]
| StopProcessingHere=true
| action-args-0=.test.directory/.foo.directory/bar
| action-name-0=transfer
| actions=1
| apply-on=check-mail,manual-filtering
| contentsA=@
| fieldA=From
| funcA=contains-not
| name=<From>:@
| operator=and
| rules=1
6. Create another folder /test/baz
7. Move foo below /test/baz. Now you've got /test/baz/foo/bar (again)
8. Open the "Filter rules" dialog
9. Select only the first filter. *don't touch the second one*
10. Press "OK". You kmailrc now reads:
| [Filter #0]
| StopProcessingHere=true
| action-args-0=.test.directory/foo
| action-name-0=transfer
| actions=1
| apply-on=check-mail,manual-filtering
| contentsA=@
| fieldA=To
| funcA=contains-not
| name=<To>:@
| operator=and
| rules=1
|
| [Filter #1]
| StopProcessingHere=true
| action-args-0=.test.directory/.foo.directory/bar
| action-name-0=transfer
| actions=1
| apply-on=check-mail,manual-filtering
| contentsA=@
| fieldA=From
| funcA=contains-not
| name=<From>:@
| operator=and
| rules=1
The second filter was not updated. Now you may have much fun with your
KMail: If now some message arrives which is processed by the broken Filter
#1, you get two nice messages:
1. Kmail says: Error opening bar. Either this is not a valid maildir folder
or you don't have sufficient permissions.
2. KNotify says: KMail encountered a fatal error and will terminate now. The
error was: Not enough free disk space.
KMail shuts down cleanly now.
Hmmm... First I couldn't reproduce it. But got another nice crash: Whenever
I click(ed) on the moved bar, I got the message "Error opening bar. Either
this is not a valid maildir folder or you don't have sufficient
permissions." The folder structure looked alright though. Could it be
possible that KMail still had the old directory cached? Whatever, I went to
the Folter dialog and deleted both the filters and pressed OK. Then I
changed to the inbox and KMail crashed again (kmail.2.bt).
Ok, that's it I think. Have fun puzzling :o)
Cheers,
Malte
