Assertion violated in filename.C:44

[Michael Gerz]

Georg,

when saving file "C:\Dokumente und Einstellungen\foo\bar\foo.lyx" (no 
non-ASCII characters), the following assertion is raised:

Assertion triggered in __thiscall lyx::support::FileName::FileName(const 
class std::basic_string<char,struct std::char_traits<char>,class 
std::allocator<char> > &) by failing check "absolutePath(name_)" in file 
C:\cygwin\home\ms\lyx-trunk\src\support\filename.C:44

FYI: The file is saved correctly. Afterwards, a dialog pops up that 
states that no backup could be created (which does not make sense 
because the backup directory mentioned does exist). As soon as I press 
OK, the assertion is violated.
