[jaunty] Totem crashes when attempt to watch DVB [DiBcom USB]. Too many open files on console

[Shaun Crampton]

Binary package hint: totem

The first time I tried DVB in Totem it worked fine but it now fails every time I try to use it. When I click "Watch TV on 'DVB Adapter 0'" on Totem's File menu, it crashes with a SIGABRT (backtrace attached). On the console, I see

$ totem
/var/lib/python-support/python2.6/gdata/tlslite/utils/cryptomath.py:9: DeprecationWarning: the sha module is deprecated; use the hashlib module instead
  import sha

** ERROR **: Error opening demuxer: Too many open files (/dev/dvb/adapter0/demux0)
aborting...
Aborted (core dumped)

The kernel documentation for /dev/dvb/adapter0/demux0 at http://www.linuxtv.org/docs/dvbapi/DVB_Demux_Device.html indicates that it returns EMFILE ``Too many open files'' if it runs out of demux filters so it's not a problem with the number of open files in the system.

With Kaffeine, I can watch DVB on this same box just fine so this is Totem/gstreamer problem.

My DVB device is a USB one (full lsusb attached):
Bus 004 Device 006: ID 10b8:0bb9 DiBcom DiBcom USB DVB-T reference design (MOD300)

totem seems to open a lot of filters.

Thank you for taking the time to report this bug and helping to make Ubuntu better. Please try to obtain a backtrace following the instructions at http://wiki.ubuntu.com/DebuggingProgramCrash and upload the backtrace (as an attachment) to the bug report. This will greatly help us in tracking down your problem.

I found that totem always opens the first channel in dvb-channels.conf when clicking the eatch TV option. If I reorder the channels then I can get totem to start with some channels and not others. Once it's started on a "good" channel, I still can't switch to a "bad" one.

I've attached my dvb-channels.conf. BBC FOUR is a "bad" channel -- switching to it crashes Totem with the above error. BBC News is a "good" channel.

the stacktrace lacks debug symbols for libgstdvb.so

Thanks for the bug report. Ubuntu-9.04 have reached EOL for a few months now, could you please try if the issue is still happening with the latest version of Ubuntu?
