Mythmusic segfaulting constantly

Reported by:… Owned by: Isaac Richards
Priority: minor Milestone: unknown
Component: mythtv Version: unknown
Severity: medium Keywords:
Cc: Ticket locked: no


I have recently begun having an issue with MythMusic in that it segfaults any time I am trying to enter it. I'm able to sync the music database, but if I try to edit visualizations from the setup menu, or play music, it will segfault. What would be a good way to try to get a handle on this? There are no intelligible error messages that I see. I recently rebuilt my machine due to a motherboard failure, and I am now running Gentoo 64-bit. Mythmusic did work initially, and I suspect that replacement of my primary monitor could have something to do with it, in that I went from 1280x768 to 1920x1080 resolution, however everything else on the machine is working better than ever.

I can't be sure at what revision it was working last, but I believe it was before some of the recent changes made in mythmusic, in which it was changed to allow it to continue playing when exiting. I have recompiled the module with debug turned on, and I will attach the output of mythfrontend and a backtrace as soon as I can get it generated.

Nevermind! I found the problem. My firewall was blocking some critical ports. I just need to define them in Kmyfirewall, and open them up. It works now.

My bad... It worked... once. Can anybody tell me what ports media-monitor uses? I'm beginning to suspect dynamic port assignment?

I've tried multiple times to get this to run, and it did work maybe twice out of 30 tries. I can't get a handle on it. I've attached a full verbosity frontend log and a backtrace after it crashed, if that will help. Let me know if I should recompile all of mythtv with debug option on if that will help. Thanks for any help you can give me!

Try compiling without LibVisual? support in MythMusic see if that fixes things. Unfortunately LibVisual? is still very buggy especially on 64bit.

Great call! I removed the visualizations use flag, recompiled amarok, removed libvisual and libvisual-plugins, and recompiled mythmusic and that seems to have resolved the problem. Unfortunately, the visualizations I enjoyed watching are gone for now, but hopefully they will get that package fixed soon. I spent countless hours on that last night trying to figure this one out. Thanks so much!

I have filed a bug report, backtrace with debug info, etc to Gentoo so they can look at the error to determine the source of the error. I will follow up with the results of that. Thanks.
