Description Armin Berres 2009-07-13 17:50:49 UTC 
Version:            (using KDE 4.2.96)
OS:                Linux
Installed from:    Compiled From Sources

I'm currently using kdevelop r995594 and can trigger a crash like this:
a) close all open files
b) Open the attached file. You will get a message that the file is non utf8 and will be opened read-only.
c) Close the dialog
d) CRASH

The backtrace looks like this:

Application: KDevelop (kdevelop), signal: Segmentation fault

Comment 2 Andreas Pakulat 2009-07-13 22:15:03 UTC 
can't reproduce this here, Armin which exact KDE version are you using?
Comment 3 Armin Berres 2009-07-13 22:57:00 UTC 
KDE 4.3 rc1 with kdevplatform svn revision 995594 and kdevelop svn revision 994808.
The latter two kindly built and packaged by Fathi Boudra, who can also reproduce the crash.
Comment 4 Andreas Pakulat 2009-07-26 03:03:05 UTC 
Hmm, without a way to reproduce this, its basically unfixable. The backtrace doesn't provide enough information and rather looks like a problem inside either Kate or Qt. Is this reproduceable with kdelibs rc3?
Comment 5 Armin Berres 2009-07-26 15:37:51 UTC 
Just tried it with rc2 and the crash still happens.
Will reproduce with rc3 ASAP.
Comment 6 Armin Berres 2009-07-27 19:07:30 UTC 
So, still happens with rc3.
Can really no one reproduce it (ok, fabo could, but apart from him)?

Just close all files, open the one I attached, click ok. Crash happens immediately.
Comment 7 Andreas Pakulat 2009-07-27 19:50:59 UTC 
Interesting, I actually can reproduce it, but only if I really had files open that I need to close. If kdevelop comes up with no files loaded and I then open the posted header there's no crash.

So probably yet another case of some kind of state of sublime/shell getting invalid :(
Comment 8 Andreas Pakulat 2009-10-17 20:07:37 UTC 
*** Bug 210898 has been marked as a duplicate of this bug. ***
Comment 9 Andreas Pakulat 2009-10-18 01:09:46 UTC 
I think this is the same cause as bug 204383, sublime's internal bookkeeping is broken.
