Stores sometimes files with the wrong mimetype

[Paradoxianer]

Files wich had already the mimetype text/x-source-code sometimes stored as text/plain.
This causes this files to not be opend buy Koder automatically..

sadly I couldnt find a "pattern" when this happens. But it happens frequently

But i need to open them in pe and save them explicit as text/x-source-code type again.
