Plasma crashes when right-click on filename in Folder View

[kubuntu-user]

In kubuntu 9.04 Jaunty Jackalope (I use the 32bit build) I found the following bug:

On a Folder View within the KDE Desktop

- select a file
- press F2 in order to rename the file
- press the right mouse button on the file name

Plasma crashes, the Desktop becomes black.

(I found this bug when I wanted to copy a file name into the clipboard.)

According to discussions in forums other users can reproduce this bug, too.

I can confirm this behaviour and set the package hint to kdebase-workspace, though i don't know if the problem is located there

[Jonathan Thomas (echidnaman)]

Could you please install kdebase-workspace-dbg and post the backtrace from the KDE crash handler? (Click the details checkbox)

Hi Jonathan,

Sorry, but the KDE crash handler does not pop up.

Seems fixed with Qt 4.5.2.

[Mark (mark-wege)]

Is there any the fix will lead to a package, so that this and other problems solved by qt 4.5.2 will work in Jaunty?

[kubuntu-user (kubuntu-user2)]

Kubuntu Natty is affected by this bug!!!!!!

[kubuntu-user (kubuntu-user2)]

Status changed to NEW.

[Christian Mangold (neversfelde)]

I can confirm this problem.
