Now I think effectively it's a bug. In the past the external utilities where

Then the shell interpreted the environment variables. This was replaced by

sure since then the environment variables has in path_prefix (if existent) will
not expanded anymore.
If we do it explicitly when calling prependEnvPath() it works for me.
Yes, you're right. QProcess doesn't invoke the shell.
LyXDir should be a special case though since there is no such
environment variable. Currently on Windows it is neccesary to write a
path_prefix with absolute paths to the configuration files (e.g.
"C:\LyXLocation\ImageMagick") because otherwise LyX won't find the
external utilities which are located in separate directories. This makes
it impossible to put LyX on a USB drive and complicates the installation
and testing process.
It would make things a lot easier on Windows if expandPath could look
for %LyXDir% and expand this to the LyX directory.
