           Summary: Header rewrite causes crash
           Product: kmail
           Version: unspecified
          Platform: SuSE RPMs
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: crash
          Priority: NOR
         Component: general
        AssignedTo: kmail-devel kde org
        ReportedBy: kgeorgokitsos nomioan gr


Version:            (using KDE KDE 3.2.1)
Installed from:    SuSE RPMs
OS:          Linux

I have been using header rewrite filters to remove mailing list names from the \
headers for some time. I upgraded to 3.2.1 A few days ago and the filters seemed to \
work ok.

I changed a filter today in the from simply moving a message to additionally rewrite \
the subject:

rewrite header - Subject - replace "\[IPCop-devel\]" - with  "*empty*" -
move message to folder "ipcop-devel"

With empty I mean nothing (I also tried entering a blank but it kept crashing)

Crashes occur repeatably but not always ( I attached two backtraces, as they look \
totally different). In addition the rewrite seems to make some mails unreadable, but \
only sometimes. As I was testing my filter I kept applying (with ctrl-j) the filter \
repeatedly to the messages that were already in my ipcop-devel folder.

As I said, I have similar filters for many mailing lists already installed and they \
seem to have been working at least until now.
