Howdy, and thank you for helping to improve Mythbuntu! I don't think upstream can use this stack trace - the symbols are missing (no fault of yours). Has this crash reoccured in the past two weeks since you first reported it?

Mario, do the latest trunk builds have debugging symbol info?

[Mario Limonciello (superm1)]

Marc:
They should be having debug symbols when processed by launchpad. If they're not, I'm not sure why that process isn't working.

[Pavel Mlčoch (pavkamlc)]

As You can see here http://ppa.launchpad.net/mythbuntu/trunk-0.22/ubuntu/pool/main/m/mythtv/ in repository isn't debug packages. I don't know if soyuz can do it.

[Mario Limonciello (superm1)]

Ah, the archive packages make debug symbols, ppa might not. We might
need to develop a better solution for ppa.

Can you confirm that this package came from the ppa and not the archive though?

As I suspected, upstream said the current backtrace isn't usable.

[Pavel Mlčoch (pavkamlc)]

No possible upload dbg package by dput? Or is planed this feature in soyuz for near future?

[Mario Limonciello (superm1)]

Pavel:

I've filed that as bug 429416 against the launchpad project.
