Description Matěj Laitl 2012-06-06 15:41:31 UTC 
Application: kdevelop (4.3.60)
KDE Platform Version: 4.8.3 (4.8.3) (Compiled from sources)
Qt Version: 4.8.2
Operating System: Linux 3.4.0 x86_64
Distribution (Platform): Gentoo Packages

-- Information about the crash:
kdevelop v4.3.1-226-g2c95298
kdevplatform v1.3.1-195-g5914f88
kdev-python beta2-6-g9031ce7
katepart 4.8.3 from Gentoo

Mt Qt build has debugging assertions enabled, you may need there too when trying to reproduce. 

- What I was doing when the application crashed:
0. plot_trajectories is a function from another python module: def plot_trajectories(TRAJ)
1. I wrote following code into editor in an opened Python project:
    trajectories = [
        [[0,0], [100,100], [300,300], [400,400], [700,700], [1100,1100]],
    ]
    plot_trajectories(t<cursor>
2. Pressed Ctrl+Space to invoke code completion
3. KDevelop asserts out

The crash can be reproduced every time.

-- Backtrace:
Application: KDevelop (kdevelop), signal: Aborted

Comment 1 Matěj Laitl 2012-06-06 15:47:26 UTC 
Oh, the assertion failure message is:
ASSERT failure in QFont::setWeight: "Weight must be between 0 and 99", file text/qfont.cpp, line 1224
Comment 2 Sven Brauch 2012-06-06 17:21:40 UTC 
Git commit b56a6d529b52d561baf66637bcee6621e785f25f by Sven Brauch.
Committed on 06/06/2012 at 19:20.
Pushed by brauch into branch 'master'.

Don't set font-weight to 255, but to 99 instead (avoids Qt assert if compiled with debug symbols)

Should fix bug 301289

Comment 3 Sven Brauch 2012-06-06 17:22:14 UTC 
Yeah, sorry. I didn't find documentation on it, and assumed it was a uchar. Setting it to 255 worked, so I didn't care any more.

Should be fixed by now.
Comment 4 Sven Brauch 2012-06-06 17:23:59 UTC 
Oh, and please use the kdev-python component to report bugs affecting kdev-python against (not kdevelop). :)
Comment 5 Matěj Laitl 2012-06-07 10:47:23 UTC 
The crash is fixed, thanks.

Sorry about that. (well, DrKonqi is also responsible, it sets product to kdevelop and doesn't let you change it - I don't know if it can handle multi-producs apps)
Comment 6 Sven Brauch 2012-06-07 10:53:20 UTC 
I see. Maybe we should report that to them as a bug? .D

Nitpicking: QFont::Bold instead of 99 would be the best here. ;)
