No, that was not it. I have tried that and even a reboot did it.
The closest I have found describing my issue it this problem report
in
WineHQ
but I cannot figure out wich versions of libjpeg to link and where,
they are not on the locations specified by this guy even though I
have both version libjpeg8 and libjpeg62 installed.
The locations of the library might be /usr/lib and /usr/lib32, if you want to recompile stuff. Also, if you have the libraries, and are under 64bits, did you make sure you had the 32bit libraries installed, something like "lib32-libjpeg6" on top of just "libjpeg6"?
My problem under Arch was solved by installing lib32-libjpeg6, so that might help you.
