Update: now it should work everywhere, please make some tests because it is not so easy to check on my linux.
A very important bug is the one where users with non-ascii characters in the
user name (or install/data directory path) causes a failure. This applies
to both Windows and Linx builds. I don't know about OSX.
I think the bug has to be fixed before 0.9.1 but I don't know how to do it.
I tried before and failed. Any help would be mech appreciated.
I am on it..
In fact, my fix might only work on UTF-8 locale systems.
To make things in a clean way the good solution is to replace all the std::string by QString in the StelFileMgr class and everywhere in the code where paths are stored.
