Bug 306571

Summary: Crash when trying to close a file [Sublime::AreaIndex::remove, Sublime::Area::closeView]
Product: [Applications] kdevelop Reporter: Marijn Kruisselbrink <mkruisselbrink>
Component: generalAssignee: kdevelop-bugs-null
Status: RESOLVED WORKSFORME    
Severity: crash CC: aleixpol

Sentry Crash Report:

Description Marijn Kruisselbrink 2012-09-10 20:43:15 UTC 
Application: kdevelop (4.3.1)
KDE Platform Version: 4.8.4 (4.8.4)
Qt Version: 4.8.2
Operating System: Linux 3.2.5-gg886 x86_64
Distribution: Ubuntu 12.04 LTS

-- Information about the crash:
- What I was doing when the application crashed:
I hit the close button of one of the files/editors that was open. (with several split views and editors for the same documents open)

- Unusual behavior I noticed:
Before the crash, I couldn't save the file in the editor I tried closing; hitting ctrl-s gave me a "ambigious shortcut" error, and clicking the save button didn't do anything either. Save all did seem to save the file at least.

-- Backtrace:
Application: KDevelop (kdevelop), signal: Segmentation fault
Using host libthread_db library "/lib/x86_64-linux-gnu/libthread_db.so.1".

Comment 1 Marijn Kruisselbrink 2012-09-10 20:47:58 UTC 
I can (at the moment) reliable reproduce it by opening the same "working set" (or whatever those sets of open documents/views are called). Trying to edit and save a file fails, closing an editor crashes.
Comment 2 Milian Wolff 2012-10-04 23:38:38 UTC 
Please give a step-by-step guide on how to setup the view/working set just how you have it. I.e. such that I can try to reproduce it.

Alternatively, please run valgrind and show us the log it produces when you reproduce the bug:

valgrind --track-origins=yes kdevelop -s ...
Comment 3 Aleix Pol 2013-04-04 00:43:37 UTC 
we need a way to reproduce it to figure out what's going on...
