scim and pinentry-gtk2

[Robby Workman]

To make a long story short, pinentry-gtk2 doesn't receive keyboard
input when scim is being used.  This has previously been reported
to both Ubuntu and OpenSuSE, and after scim and friends were recently
added to Slackware, we're seeing it there.

Any idea what's at fault?
