Sentry Crash Report:
Attachments: File that causes the crash

Description Daniel Vrátil 2013-09-09 10:13:41 UTC 
Application: kdevelop (4.5.60)
KDE Platform Version: 4.11.00 (Compiled from sources)
Qt Version: 4.8.5
Operating System: Linux 3.10.10-200.fc19.x86_64 x86_64
Distribution: "Fedora release 19 (Schrödinger’s Cat)"

-- Information about the crash:
- What I was doing when the application crashed:
I started KDevelop session (with all  KDE Telepathy projects), it started parsing files and suddenly crashed on a QML file (judging from the backtrace).

This happens every time, but I don't know which file triggers the crash. Reproducible on latest git build of kdevplatform, kdevelop and kdev-qmljs.

The crash can be reproduced every time.

-- Backtrace:
Application: KDevelop (kdevelop), signal: Aborted
Using host libthread_db library "/lib64/libthread_db.so.1".

Comment 1 Milian Wolff 2013-09-28 16:02:01 UTC 
I'll need the QML file for that. Please enable the language debug area (9505) in kdebugdialog and then start kdevelop from the CLI and note the debug output. The last lines of  the format "creating parse-job KUrl("file:///home/m...") new count of active parse-jobs: 2" are interesting. Take as many lines of that as you like, though up to what ever you configured as max num of parse jobs should suffice. Then open them in a standalone kdevelop session to figure out which file it is.

File that causes the crash

Attached is the file that causes KDevelop to crash.

Output from KDevelop:

Comment 3 Milian Wolff 2013-09-30 21:50:38 UTC 
Jup, can reproduce. This line confuses the plugin:

     property QtObject theme: PlasmaCore.Theme {}

I'll try to fix it once I have some more time. Lets see :)

Git commit 29a72f5c1234f1a47404e02d763da923be97fb58 by Milian Wolff.
Committed on 30/09/2013 at 22:08.
Pushed by mwolff into branch 'master'.

Support UiObjectInitializer without ClassDeclarations.

This is valid QML and thus must be supported. In the future we
might want to create ClassDeclarations for UiObjectBinding as
well though.
