blootube-wide & video settings: unknown tag image crashes frontend

[ikke@…]

I have experienced this problem with couple versions of trunk with few weeks difference. System is Ubuntu Gutsy. This happens while trying to enter into video settings (I guess video-plugin) from settings menu. Gui freezes for minutes, and then mythtvfrontend crashes.

Here's the latest log trace:

I don't know why I can't get backtrace. I did svn update, compiled with --compile-type=debug, installed. Both for mythtv and mythplugins trunk. Then restarted backend, followed the instructions in myth manual to take backtrace with gdb, also by giving the commands within gdb, but still I don't get trace! WTF?

ok, like Aaron adviced me, it was kernel that kills memory hungry beasts. It seems 1 GB is not enough for the theme ;)

Just tell me what more you want me to trace this one... it seems to be randow sw which gets killed by oom-killer, but it gets triggered always by going to this utilities/setup-> setup -> media -> video settings with blootube-wide. The other theme (neon-wide) doesn't do this.

Entering the plugin menus causes the images used for that plugin to be loaded (even if they are already loaded for use in mythfrontend). I've a task ticket open for this issue and it would be solved by moving the existing image "cache" to become a global cache covering all plugins loaded by mythfrontend.

Most likely the reason Blootube-Wide causes problems but Neon doesn't, is because it uses larger images which consume more memory.

I'm going to close this, since there is a ticket open already and the crash described here isn't caused directly by mythtv but by the kernel.
