Backend crashes during poor reception on saa7146 card

I have 2 DVB-T tuner cards in my system - a cx88 card (Hauppauge Nova-T) and a saa7146 card (TechnoTrend? TT-Budget-T-1500). The former card is used for most recordings, and the latter used as a second resort and for a limited number of extra channels (Top-Up TV).

Reception where I am is pretty dreadful, and it's not uncommon for recordings to skip and jump where chunks of the signal are lost. However, when recording with the TechnoTrend? card, there is a VERY high likelihood of the backend crashing during these patches of poor reception - often several times during a single show.

Attached is a backtrace taken during a recording from the TT card.
