Bug#776686: libwebkitgtk-3.0-0: Crash with SIGBUS in `WebCore::WidthIterator::advanceInternal`

[Tobias Frost]

Control: severity -1 normal


Hi Paul,

all good things are three ;-)

Same as on the first one, please tell how often sometimes it. This is
for sure not critical. Your described
scenario is not _serious_ data loss. *Serious* would be if it wipes
half of your filesystem, for example, but not a single text with so
many ifs and whens )
Again, if you are different opnion, please clarify and lets discuss.
