It definitively fail here. Tried with this code:
Function KeyDown(Key As String) As Boolean
dim p As Picture
dim s As String
p=new Picture(32,32,32)
p.Graphics.DrawOval 0,0,31,31
s=PicturetoBinaryStringMBS(p)
p=nil
End Function
(the p=nil function is just where I put the breakpoint, because a bug
in RB prevents me to use "break" (the involved event is not shown with
using "break")).
I get an empty string.
Note that all this (both the former app and the testing app) are
remote debugged.
I can say some other pictures functions aren't working (e.g the one
that converts to sepia).

"sort of". I have them with an extra ".0" at the end of the name
("libgtk-x11-2.0.so.0" and "libgdk-x11-2.0.so.0"). I even have a
"libgdk-x11-2.0.so.0.2000.1". However, not with the exact same name
you mentioned. I don't know if Linux reads from left to right or
expects the correct file name...

Of course. It's just that I've had some bugs that could not be
resolved in the past (I've taken the habit).
