I've done a little more debugging and found out, that the problems only occur if psi is configured with --disable-bundled-qca (which is the case in the ubuntu packages) and the package libqca2-plugin-gnupg is installed.
After uninstalling the package my problems were gone.
With knowing this I could recreate the bug on another system simply by installing libqca2-plugin-gnupg.
Please rename the bug something like 'libqca2-plugin-gnupg breaks psi'.
