Binary package hint: tvtime

Upgraded to Lucid on top of running Karmic System. New install from standard Synaptic repos of tvtime. Newly connected Pinnacle USB tuner. tvtime shows SEGFAULT on start in kern.log (attached). Sounds like bug #575938 but no other USB or external devices attached.

I experience the same error on Xubuntu 10.04 x86, Acer Aspire One D250.
When I try to launch tvtime, it shows the main window for a moment and then closes.
After that, dmesg|tail shows

tvtime[12203]: segfault at 6b0 ip 0804d824 sp bfaa584c error 4 in tvtime[8048000+76000]

[Markhor (markhor)]

I forgot to mention that I launch tvtime with or without tv usb module (AverTV Pilot in my case), it does not matter.
