Bug 300820

Application: dragon (2.0)
KDE Platform Version: 4.8.3 (4.8.3) (Compiled from sources)
Qt Version: 4.8.1
Operating System: Linux 3.2.12-gentoo x86_64
Distribution: "Gentoo Base System release 2.1"

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

I simply ran "dragon MOV0689.MPG".  The window came up, I saw the first frame, heard a blip through the speakers, and then got this crash.  Trying another (smaller) movie from the same camera produces the same results

$ file *MPG
MOV06981.MPG: MPEG sequence, v1, system multiplex
MOV06989.MPG: MPEG sequence, v1, system multiplex
$ ls -l *MPG
-rwxr-xr-x 1 dmcbride dmcbride  11778420 Mar 17 20:52 MOV06981.MPG
-rwxr-xr-x 1 dmcbride dmcbride 536299861 Mar 18 20:00 MOV06989.MPG

Both of these work fine in vlc.

Using the gstreamer backend (not sure if relevant)

gstreamer 0.10.35
phonon-gstreamer 4.6.0

I can share the movie(s) with whomever (they're just my kids' birthday party), but they're probably too big for bugzilla.

The crash can be reproduced every time.
