Description Vadym Krevs 2004-12-16 10:29:20 UTC 
Version:           3.1.2 (using KDE KDE 3.3.2)
Installed from:    SuSE RPMs
Compiler:          gcc 3.3.5 
OS:                Linux

Hi. I use Kdevelop on Suse Linux for all work on our company's 5000+ file software app (~128Mb source code). For that I've created a "Generic C++ application (custom makefiles)" project. Usually KDevelop starts, opens the last used project, and reopens all source files (in different tabs) that were opened before exit. However, occasionally, when I click on a different tab to switch to another file, or try using CTags lookup, or minimize/maximise the entire Kdevelop application window, Kdevelop crashes with a SIGSEGV, and the following stack trace is produced:

Using host libthread_db library "/lib/tls/libthread_db.so.1".

Seams to be a kate issue. mattr, teatime ?
Comment 2 Vadym Krevs 2004-12-16 12:57:12 UTC 
I forgot to mention that I use the FTP version of Suse Linux 9.1.
Comment 3 Matt Rogers 2004-12-16 15:45:32 UTC 
without a better backtrace, I would say that it is a kate issue. Probably the easiest way for us to tell is if it's reproduciable using kate or not. However, these two lines:

#8  0x4221ad2a in QXIMInputContext::setMicroFocus () 
    from /usr/lib/qt3/plugins/inputmethods/libqxim.so 
#9  0x421e73a3 in QMultiInputContext::setMicroFocus () 
    from /usr/lib/qt3/plugins/inputmethods/libqimsw-multi.so 

make me think it's a bad interaction with a qt plugin. We can't really pin it on anything yet.
Comment 4 Jens Dagerbo 2004-12-16 17:56:31 UTC 
This is invalid and a dupe. SuSE patches Qt and it's the added code that crashes. I'll find the dupe tonight and close it unless someone beats me to it.
Comment 5 Jens Dagerbo 2004-12-16 23:07:12 UTC 
Dupe.

Now the same happens on Suse 9.2 Professional. However, Kdevelop is the only KDE application that crashes.
Comment 7 Amilcar do Carmo Lucas 2005-01-20 11:29:32 UTC 
Well, have you read the comments ?
SuSE RPM's are broken, uninstall KDevelop and compile KDevelop HEAD locally on your machine. The crashes, and 140 bugs should disappear.
