I have a problem which makes Geany completely unusable. Tying any character into a document causes the system to lockup with 100% CPU for about 5-10 seconds. I can use the menus, but typing anything into the document has the same effect.
I'm not sure if this started when I upgraded Ubuntu from 11.10 to 12.04 or if it was because Geany upgraded.
I tried removing the apt package and deleting ~/.config/geany and installing Geany 0.21 from source, but the same thing happened.
I downloaded version 0.20 and installed from source and the problem is not there.
I'm using GTK 2.24.10 and GLib 2.32.1 on Ubuntu 12.04, 3.2.0-24-generic kernel, x86_64
