Description Vishesh Handa 2010-06-17 13:15:48 UTC 
Application: kdevelop (4.0.60)
KDE Platform Version: 4.4.85 (KDE 4.4.85 (KDE 4.5 Beta2)) (Compiled from sources)
Qt Version: 4.6.2
Operating System: Linux 2.6.32-22-generic i686
Distribution: Ubuntu 10.04 LTS

-- Information about the crash:
- What I was doing when the application crashed:
This hapens sometimes. When I close one of the files open by clicking on the X sign on the tab bar, kdevelop crashes. It's kinda annyoing. It's happened 5-10 times now, but it's rather unpredictable.

I'm using the latest KDevelop from git. "git show" gives me -
commit 21d78fbdfeb6620bfaf42711dd9078c7044625f0

The crash can be reproduced some of the time.

-- Backtrace:

Comment 2 Milian Wolff 2010-06-17 14:25:10 UTC 
You don't need to, it's a known bug with the SmartRanges. Should hopefully be fixed with David's rewrite that will use the MovingRanges that are introduced in Kate for KDE 4.5.

Closing for now, as it's being actively being worked on and it's a known bug (probably there are duplicates somewhere available...)

Changing the product back to kdevelop. Otherwise, the bug reporting assistant will never find this report.
Comment 7 Nicolas L. 2010-06-24 14:56:03 UTC 
oh yes sorry
Comment 8 Milian Wolff 2010-07-01 20:35:39 UTC 
Christophe Giboudeaux just provided me with the valgrind infos below. Even though parts of the line numbers/debug info look fishy, I'm tempted to say this should be all we need to fix it.

To me it looks as if one need to unset watchers on SmartRanges before deleting the watcher. I'll have to find out which widget actually causes that, probably the problem highlighter itself - but why is that getting deleted before the KateDocument?
