Libreoffice does not save files in the opened folder when folders containing umlauts "äöü" nor it will export pdfs there.
After opening a file within a folder containing umlauts (äöü), the file will not be saved in the same folder (directory). It will be saved in \\documents (or somewhere else).
This affects all german!!
Please fix it.
Can't reproduce on OS X. Looks like a Windows only issue.
This is not critical, because no data is lost. You can still save to another location. Reducing to "major" since it's still ugly.
