Public bug reported:

Affects: gucharmap (Ubuntu)
       Severity: Normal
       Priority: (none set)

Description:
gucharmap (Applications → Accessories → Character Map) crashes when I
scroll down the Latin character set using the mousewheel. This happens
every time.

To reproduce:
1. Start said program
2. In the script pane, select Latin (I tried a couple of others but only Latin caused the crash)
3. Scroll down in the character pane with the scrollwheel.
4. crash

My setup:
Dapper Beta with all the newest updates.
Linux 2.6.15-20-k7 #1 SMP PREEMPT
