Not very enlightening, unfortunately. Line 44676 is: *pMeta = get4byte(&pBt->pPage1->aData[36 + idx*4]); Offset 0x70 means that the pPage1 member is zero at this point. Obviously, this should not happen. It's not really a smoking gun. The next step would be to attach a debugger and examine what SQL statement is being executed. (It's not clear that this is an SQLite bug at this point, but Iceweasel needs to something rather invasive to cause this particular failure, like scribbling over random memory.) -- To UNSUBSCRIBE, email to debian-bugs-dist-requ...@lists.debian.org with a subject of "unsubscribe".
