Version:           1.5.5 (using KDE KDE 3.5.5)
Installed from:    Gentoo Packages
Compiler:          gcc version 3.3.5-20050130 Gentoo 3.3.5.20050130-r1, ssp-3.3.5.20050130-1, pie-8.7.7.1
OS:                Linux

* How to reproduce:
Hold Shift key and press right arrow.

It's strange, but for me it is causing a crash.
Console output:

---cut start: console output---
$ umbrello
KCrash: Application 'umbrello' crashing...
KCrash cannot reach kdeinit, launching directly.
$ _
---cut end: console output---

The more strange is that with Ctrl pressed nothing happens. Crash occurs only when I press ONLY Shift + right arrow.

GDB output after pressing that key combination:

---cut start: GDB output after pressing Shift + right arrow ---
Program received signal SIGSEGV, Segmentation fault.

Program exited with code 0375.
