According to a crashreport MythTV didn't shut down properly

[Arjen]

Binary package hint: mythtv

Every time I exit MythTV's frontend (using ESC and than hitting 'yes' at the prompt) I see a 'crash detected' pop up, so something is not cleanly closed or communicated. This happens since I've upgraded to ubuntu 10.04 alpha somewhere a while back.

Howdy, and thank you for helping to improve Mythbuntu by opening this ticket. The log files seem to indicate two problems, probably releated to each other:

Problem 1: mythflix 0.22 is installed:

2010-02-28 00:41:52.744 Plugin mythflix (0.22.20091023-1) binary version does not match libraries (0.23.20100225-1)
2010-02-28 00:41:52.744 Unable to initialize plugin 'mythflix'.

Solution 1: unfortunately the only solution is to remove mythflix - it does not work with 0.23
Problem 2: Probably because mythflix is installed, your other plugins are not updated to the correct version:

2010-02-28 00:41:52.650 Plugin mytharchive (0.23.20100212-1) binary version does not match libraries (0.23.20100225-1)

Could you please report back after you remove mythflix via package manger, then update your packages, and then perform any upgrades?

[Arjen (acm-tweakers)]

I don't care about that particular plugin so I removed it. There are no upgrades left, perhaps a 'dist-upgrade' had already forced the newer packages (my logs don't seem to rotate since my system is hardly ever powered on after midnight).

The crash report seems to be for mythv's backend rather than its frontend, even though it appears after I exit from the frontend (or perhaps it takes some time to report and I don't see it because mythfrontend is started full screen normally). The weird thing is though, mythbackend is still running when that claim is made.

I can only reproduce it by rebooting the system, just 'restart mythtv-backend' doesn't seem to trigger things. But given that my system hasn't been upgraded very well with 10.04, perhaps some other failing package may be responsible. For instance the fact that my gdm/X doesn't always start.

[MarcRandolph (mrand)]

I missed something previously on your frontend log:
2010-03-20 09:59:49.754 LookupUDN()- bad device type '', not enough tokens
Error in my_thread_global_end(): 1 threads didn't exit

The above makes me think that it is your frontend crashing, although I'm not certain why (except for MythFlix). Having said that, your backend log does have a troublesome entry:

2010-03-20 09:58:41.875 MythBackend, Error: No valid capture cards are defined in the database.
   Perhaps you should re-read the installation instructions?

I'd suggest the following actions:

0. Re-run mythtv-setup that capture cards and inputs are assigned
1. After doing an apt-get update, if apt-get upgrade doesn't show anything, perhaps do a dist-upgrade again, or do a apt-get install mythplugins just to make sure
2. rotate your logs so that it's clear what the current errors are (especially now that you removed mythflix) and reattach fresh logs to this ticket

[MarcRandolph (mrand)]

BTW, I don't believe that the following error message is fatal, but it makes me wonder there is a problem with your theme install:

XMLParseBase, Error: Unable to load window 'backgroundwindow' from base

[Arjen (acm-tweakers)]

Ok, I rotated the log just before rebooting. So the mythtv backend log contains one start using 'restart mythtv-backend' and one bootup. Mythtv frontend's log now only contains the bootup.

Apart from that, I'm more convinced its the backend that's supposedly "crashed". About the backend-log, I don't have a caption card, nor any other special input device. Mythtv on that box is only used to have a fancy, tv-screen readable, interface for playing video files and dvd's. But this time the message also appeared (after a while) with myth frontend still running.

The mythplugins-package was not installed, as I've upgrading this box from somewhere around the 8.04-age (including most of the pre-release beta's and some of the alpha's of the new mythbuntu/ubuntu's) it may very well be some messed up installation.

I've attached the fresh mythtv backend and frontend logs.

[Arjen (acm-tweakers)]

It appears to have gone away with one of the updates lately. I.e. myth-backend's potentially crashing is not reported anymore, so it probably doesn't crash anymore :)

[MarcRandolph (mrand)]

Thank you for reporting back! Closing bug.
