Product: [Applications] digikam Reporter: Tristan <trisroger>
Component: Tags-EngineAssignee: Digikam Developers <digikam-bugs-null>
Status: RESOLVED FIXED    
Severity: crash CC: caulier.gilles

Description Tristan 2011-04-30 03:47:45 UTC 
Application: digikam (1.9.0)
KDE Platform Version: 4.6.2 (4.6.2)
Qt Version: 4.7.2
Operating System: Linux 2.6.38-8-generic x86_64
Distribution: Ubuntu 11.04

-- Information about the crash:
- What I was doing when the application crashed:

Was trying to delete unwanted/unused tags quickly.  Pressing. "right click" > "d" > "space" was the quickest way (2-3 per sec).  3 times I got into a rhythm and digikam crashed.  

Just post Kubuntu 11.04 upgrade, but had not tested prior to upgrade.

The crash can be reproduced some of the time.

-- Backtrace:
Application: digiKam (digikam), signal: Segmentation fault

Comment 1 Marcel Wiesweg 2011-04-30 22:26:31 UTC 
This is a bug of a reentered event loop. Three times recursive in fact (ContextMenuHelper::exec -> KMessageBox -> ...) I'll need to think how to best prevent that. Normally, the message box should be model so that subsequent events are not generated, but obviously event are already in the loop and then processed.
Comment 2 Marcel Wiesweg 2011-05-15 17:01:37 UTC 
Git commit 59e5acd4f132b3b585644d2f470e79b3bb185284 by Marcel Wiesweg.
Committed on 15/05/2011 at 16:51.
Pushed by mwiesweg into branch 'master'.

Strictly use AlbumPointer safeguards whereever a dialog (=event loop) is entered.
Remove the parentTag mechanism, instead store the tag in the QAction.
Hopefully fixes the crash on rapid deletion with recursive event loops.

BUG: 272023
