           Summary: kDevelop hangs when importing existing project
           Product: kdevelop
           Version: unspecified
          Platform: Gentoo Packages
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: NOR
         Component: general
        AssignedTo: kdevelop-bugs kdevelop org
        ReportedBy: peter.waller gmail com


Version:           3.5.2-r1 USE="fortran haskell perl python ruby -ada -clearcase \
-cvs -debug -elibc_FreeBSD -java -pascal -perforce -php -sql -subversion -xinerama" \
(using KDE 3.5.9) Installed from:    Gentoo Packages
Compiler:          gcc (GCC) 4.1.2 (Gentoo 4.1.2 p1.1) 
OS:                Linux

I am simply trying to edit some existing code from the ROOT project

http://root.cern.ch

Code was obtained with:

svn co https://root.cern.ch/svn/root/trunk root

If I try to import the whole project, kDevelop hangs, using 100% CPU. If I attach \
strace, I can see that nothing is happening, it is frozen on an futex line.

So instead, I tried creating the project and not importing any files. Additionally, I \
turned all plugins off. Then I added just one or two files and directories, which \
occasionally works, but sometimes leads to the same crashing behaviour.

<<snip>>
ioctl(3, FIONREAD, [0])                 = 0
gettimeofday({1217730028, 89564}, NULL) = 0
select(14, [3 4 5 7 9 11 12 13], [], [], {0, 25}) = 0 (Timeout)
gettimeofday({1217730028, 92813}, NULL) = 0
gettimeofday({1217730028, 92891}, NULL) = 0
futex(0x823867c, FUTEX_WAIT, 2, NULL
<<nothing happens>>

Here is a backtrace:

If I kill it and I try to re-open the project I made with it, it hangs again.

I hope this is enough information, let me know if more information is needed.

Regards,
