Segfault when Trying to Start ProjectM Visualization

[skd5aner <skd5aner@…>]

Backtrace and Log included

Recently, after upgrading to .22-fixes, I discovered a segfault when trying to utilize the ProjectM visualizations without a segfault. (as a note, when I upgraded to .22-fixes, I simultaneously upgraded to ubuntu 9.10 from 9.04). I have tested the majority of the other mythmusic and libvisual visualizations, which appear to be functioning as expected. While I'm not too worried if ProjectM works or not, it should probably not segfault mythfrontend. I honestly don't think I've ever had ProjectM work for me, but I know it didn't segfault in any previous version of myth since it's inclusion.

Here's how I can replicate it: 0) Set the order of visualizations to be Album Art, followed by ProjectM 1) Start Mythmusic 2) Start playback of any song 3) Press 4, to bring the visualization full screen, this will show the cover art image. 4) Press 6, to switch to the next visualization - SEGFAULT

I'm running .22-fixes, r22954 mythfrontend --version Please include all output in bug reports. MythTV Version : 22954 MythTV Branch : branches/release-0-22-fixes Network Protocol : 50 Library API : 0.22.20091023-1 QT Version : 4.5.2 Options compiled in:

Sorry, typo - Should Read: Recently, after upgrading to .22-fixes, I discovered a segfault when trying to utilize the ProjectM visualization.

I think the solution is to remove Project-M support (if not visualisers generally) since no-one is willing to maintain it and it's a constant source of crashes.

The port of MythMusic to mythui will remove the libvisual support because it's buggy and no longer supported. I may look at adding Project-M as a native visualizer but probably not for the initial release.
