MythGallery fails to show EXIF information (QPainter)

[otto at kolsi dot fi]

MythGallery fails to show EXIF information for photos in one particular machine. EXIF info can be seen on another frontend just fine. One difference is that machine which has problems has older card (nVidia 5200) and older drivers (if this has anything to do with it).

When problem occurs, following is printed to logs:

QPainter::begin: A paint device can only be painted by one painter at a time.
QPainter::initFrom: Painter not active, aborted
QPainter::end: Painter not active, aborted

The grey background image for EXIF info is shown but there is no EXIF texts.

I can't reproduce this with trunk [25660]. Is this still a problem, and if so, what version are you running?

Confirmed on IRC that the problem remains for the user with trunk. He's configuring with:

./configure --previous
Options:  --qmake=/usr/lib/qt4/bin/qmake --disable-audio-jack --disable-joystick-menu 
--disable-firewire --disable-ivtv --disable-v4l --disable-hdhomerun --disable-iptv 
--enable-dvb --enable-opengl-vsync --enable-opengl-video --disable-xvmc --disable-mheg 
--enable-silent_cc --compile-type=debug

Just in case this has any effect on the problem.

(In [25780]) Always explicitly end painting with a QPainter instance when we're finished. Fixes the EXIF display bug. Fixes #6771

Please re-open if you can still reproduce the bug following this commit.
