Evolution forwards attachment in dat format sometimes

Hi all

I’m running Evolution 2.30.2 in opensuse 11.3 and for some reason, evolution forwards email or attachments in .dat format sometimes. Strange this is, in my sent folder, the attachment shows correct format, but the recipients get dat file. This doesn’t happen all the time though, so I wasn’t able to narrow down the potential issues yet.

Any help will be appreciated.

Thanks
