TDE 3.5.13.2 : Missing icon in start menu

OK I've reproduced this in 3.5.13.2, in openSUSE 12.2 .

Initial case: I have a top-level category in start menu that have an invalid icon, so there is no icon displayed at all for this category (see attached picture).
I want to fix the icon, so I open kmenuedit

In kmenuedit, I select the category with missing icon.
In the right pane, I click on the big icon to open the icon selector.
In the icon selector window, I type any string in the search field, so that icons are filtered in the list. It works.
Then I erase the text in search field, by pressing backspace several times.

When the search field gets empty (no more filter), kmenuedit crashes with SEGV.

Backtrace:

Can you install the tdelibs debug symbols, then regenerate the backtrace?

Thanks!

Here is a gdb backtrace with debug symbols installed:

Grrr it looks like I'm having troubles generating debug informations under opensuse, I will try to reproduce the bug in another distribution.

Finally, I've managed to get a backtrace with tdelibs debug informations.

This is happening on openSUSE 12.2. Unlike what I thought before, it is not related to missing/incorrect icons. It happens on any item in kmenuedit, even when everything is correctly configured.
I cannot reproduce this on the other distro I tried (CentOS 6).

I cannot duplicate this bug in GIT (2013-05-22). Pressing Backspace until the text box is empty does not result in a crash. Nothing happens. No crash either when using the Clear widget to remove the text from the text box.

I will try to reproduce this soon, BUT It was caused when having invalid "KDEDIRS=/usr" variable set by older "startkde" script version, and KDE4 was installed under /usr.
The crash has vanished when setting KDEDIRS="/opt/trinity:/usr" .

Still, it's a crash and should not occur even when using "/usr" icons from KDE4.

Francois, is this report still valid?

No, it is workarounded since we have renamed "applications.menu" to "tde-applications.menu".

Tagging as resolved. Refer to git commit 5da63fe9 2013-07-31 in support of bug report 1563 for the resolution.

Thanks for reporting and helping!
