immediate segfault when selecting "Watch Videos"

[Klavs Klavsen <kl@…>]

When I select "Media library"->"Watch Videos" mythfrontend immediately segfaults.

I'm running mythbuntu 0.22 with myth* packages from their weeklybuilds: ​http://weeklybuilds.mythbuntu.org/mythbuntu/trunk-0.22/ubuntu

mythbuntu package version:0.22.0+fixes23003-0ubuntu0+mythbuntu3

mythtv-dbg is installed.

I've attached a backtrace - which doesn't tell me anything - but I've never seen a backtrace before.. I hope it helps you - or perhaps you can tell me what to do differently to debug.

I forgot to mention, that this problem does not occur on any of my other frontends (which are not using packages from mythbuntu weeklybuilds though - as they are Debian Sid and Ubuntu 9.04 machines) using the same backend.

Not that this isn't a bug in its own right, but can you check and see if the video directory is blank?

Utilities/Setup->Setup->Video Settings->General

I suspect that this would go away if you populated the field (if it is indeed blank). Mythbuntu is blanking out this field in their own DB modifications, I believe, which I suspect is causing this.

If I choose "Video Settings" it also crashes instantly. both with the "weekly build" from mythbuntu and with orig. ubuntu packages.

can I provide more info?

Klavs,

Can you get me a backtrace for the crash trying to enter the settings also, then, please?

Thanks.

I just confirmed that mythvideo is same version as the rest (0.22.0+fixes22594-0ubuntu1 - I reverted to this, to get mythtv-dbg - it isn't in mythbuntu weeklybuilds it seems).

I've attached the backtrace from entering the video settings.

(In [23083]) Refs #7805. Not entirely certain this will fix the issue but it's the first thing that jumps out at me. Check to make sure the dirlist has any values before attempting to operate on it.

(In [23084]) Refs #7805. Backport what should be an otherwise harmless change so that ticket reporter can test possible fix with nightly pacakged builds.

Klavs,

Once r23804 hits your nightly builds, can you please test and report back on whether in fixed/changed your issue?

Thanks.

[Klavs Klavsen <kl@…>]

I will. Thank you for the fix..

23084 has landed - and it works like a charm. The field for the path to the videos was indeed empty - but now I could set it and voila :)

Thanks for reporting back.
