running kde 3.5.4 from build tree on a 10.1 x86_64 installation, and kmail can't decrypt gpg-encrypted messages. when i try to open such a mail, a window flashes over the screen (i assume its the "enter passphrase" dialogbox), disappears as soon as it appears, then kmail tells me "wrong passphrase". same kde version on a 10.0 x86 installation works fine. and before i copied my home directory to that x86_64 box, it worked as well.
Any ideas for me?
