This crash happened in Brief RSS ( ), for some feeds. It looks like it never happens for text-only feeds but I'm not sure what kind of non-text content trigger the crash. Some frequently crashing feeds (for me) are:

Sorry, I may have been unclear on one point: the crash happens whenever I try to view one of these feeds. What I meant by "frequently" is that it looks like only some feed entries trigger the crash, and these feeds appear to get a new crashing feed entry frequently.

Thanks Lionel,

I will first ease the crash problem. And try to fix the real cause later.
