Bug 130530

Version:           1.5.3 (using KDE 3.5.3, Gentoo)
Compiler:          gcc version 3.4.6 (Gentoo 3.4.6-r1, ssp-3.4.5-1.0, pie-8.7.9)
OS:                Linux (i686) release 2.6.11.11

Switching from tab to tree view crashes umbrello-1.5.3:

1. Open a file (or create a new one)
2. Uncheck Settings -> Configure Umbrello UML Modeller -> General -> Miscellaneous -> Use tabbed diagrams
3. Click OK
