Version:           unknown (using 4.4.2 (KDE 4.4.2) "release 234", KDE:KDE4:Factory:Desktop / openSUSE_11.2)
Compiler:          gcc
OS:                Linux (i686) release 2.6.31.12-0.2-desktop

After several rearrangements of menu (adding/removing/renaming menus, moving/changing menu items) KDE Menu Editor refuses to save changes. The progress bar indicator infinitely loops, and no changes really happens (according to applications-kmenuedit.menu and *.desktop files modification).

After the program restart most of newly added menu items (as well as some already existing ones in related menus) are empty, and some garbage folders appear.

Restoring default system menu (of KDE Menu Editor) doesn't work.

Removing ~/.local/share/applications/* and ~/.config/menus/* doesn't help.

So as nobody posted alike bug (except for some portuguese guy about three years ago, I don't remember the bug number), it's related either to rarely factors combination, or to system corruption (I've encounted recently the situation when updating KDE from 4.3.5 to 4.4.2 led to KDE desktop crash, it dissapears after switching to Factory repository). Or probably some locale issues.

But it's a very disappointing bug.

Platform: openSUSE 11.2, KDE 4.4.2-234.1.
