Hello:)

Using Neon KDE-NIGHTLY packages (20090106+svn906850) I encountered a kate crash.

First time Crash. Situation was :
- working on highlighted PHP file
- no code-folding was activated
- just came from another application by alt+tabing, at same time I was moving the mouse to select some content in Kate
- pressed the delete key to remove a few words

Then <Crash>

I can't really reproduce this problem because the action steps are quite simple and would usually always work.
I guess only the speed of doing it and the rather busy state harddrive I/O of my computer did matter.

Backtrace:
Application: Kate (kate), signal SIGSEGV

maybe related: bug #192961, bug #192961.
A reliable way to reproduce would be appreciated.

From bug 220017:

What I was doing when the application crashed:
I was working in Kile, typing text (no special characters) and/or moving the
mouse, and it suddenly crashes...

It was at 01:30 so it might be related to autosave (which is configured to
trigger every 30 mins).

From bug 245443:
I searched a .CPP document for a token, and KWrite crashes when I pressed
"Continue searching"

From bug 256915:
I marked a bookmark, then scrolled all the way to the beginning of the document
and then went to the bookmark I previously marked with the Bookmarks menu. Kate
crashed right after that.

I don't know what could have caused this. I had firefox opened, two nautilus
windows, and a terminal window. The document was a java source file with more
than 1000 lines of code. There were few bookmarks (no more than 8).

From bug 257929:
-- Information about the crash:
I just was coding a script in php 5 when Kate crashed and those two times.

From bug 264654:
I had a some .phtml files open (Magentos html/php files)
Then I surfed some in Opera and then KATE crashed.
I wasn't currently editing any files.
KATE has been up and running all day, and I never noticed any problem.

Sorry, without an updated backtrace for some KDE >= 4.6 we can't do a lot here :/ Code changed a lot since then. Beside I hope current Kate codecompletion GSoC will rewrite that parts

Comment 27 Dominik Haumann 2011-10-19 18:41:29 UTC 
I thought it's fixed for KDE 4.8?

Comment 30 Dominik Haumann 2012-02-19 08:31:50 UTC 
As code folding changed quite a lot in KDE 4.8, we assume this is fixed.

However, if anyone sees this bug in KDE >= 4.8 again, please reopen.
