[FreeNX-kNX] Application freezes on tooltip with linux client

[Mike Martin]

The trouble seems to be with tooltips produced by an app that was built
using glade-0.6.x and is therefore a gtk+1.2.x app.

Note that all tooltips on gnome panel work fine.

This behavior is only seen in the linux client, the NX Client for
Windows displays all tooltips fine.
