[Pkg-kde-extras] Bug#761473: libkexiv2-11: Crash with Floating point exception on special mp4 videos

[ewl+debian+nospam2014 at lavar.de]

reassign 761473 libkexiv2-11 4:4.14.0-1+b1
severity 761473 normal
retitle 761473 libkexiv2-11: floating point exception on special mp4 videos
stop

Hello again,

I finally found where the problem is coming from (well, kind of): I had 
downloaded mp4 files recorded on a Galaxy S with a CM11 firmware, and 
the files have a format which seems quite special, as vlc, avplay and 
mplayer have also their problem with those films BUT they don't crash!

Whereas digikam and gwenview both do crash on a directory with those 
files (and don't without them), meaning the issue is indeed rather at 
lib(k)exiv level. As the bug reports I referred to seem to hint at the 
fact that libkexiv is responsible for error handling, here we are!

I can share privately the offending files if someone is willing to fix 
the issue, which is less important than initially thought.

I hope all the bug control commands are correct...

Thanks, Eric
