[REVIEW] fdo#48601 FILEOPEN: Open Visio's file with bitmap's blocks

[Julien Nabet]

Hello,

fdo#48601 contains 2 files and mixes display problem and crash.
Even with the last fixes on Visio, I had crashes for both files.

1) First file
I pushed a patch on master for contrib/libvisio and lo/libvisio for the 
first attachment of the bugtracker.
The problem is with characters now, see 
https://bugs.freedesktop.org/attachment.cgi?id=63115&action=edit
Certainly a link with fdo#48602, see 
https://bugs.freedesktop.org/show_bug.cgi?id=48602#c0 :

Anyway, would it be ok to cherry pick the crash fix to other branches ?

2) Second file
I'm a bit stucked. See the bt here : 
https://bugs.freedesktop.org/attachment.cgi?id=63108&action=edit
I searched about where colours counting would be different but got lost :-(
Any idea ?

Julien.
