Choosing colors from palette crash

[Kendzi]

I try to chose color for drawed lines. I do it by moving mouse under color palette at the bottom of inkscape window and right clicking on color and the from pop-up menu I chose "Set fill". It is working few times but after that it stops. Right clicking on palette don't work pop-up menu don't appear at all. After next few attempt inkscape generate error message as shown in attachment. I try to use inkscape version 0.48.4 r9939. After restart the problem repeats. It is not possible to use Inkscape for me without choosing colors.

Really no one care?

I run Inskape from console. When that bug happen this error is printed:

Bug #1323815 looks very similar...

The error messages are not exactly the same, but yes, it looks very similar.

Not reproduced on Windows XP, Inkscape 0.48.4 and trunk revision 13882. Maybe my test was too short (only ~50 tries). Any idea on how long it took you to run into the issue?
And does it happen with any color palette, or with a specific one (I've limited my tests with the Inkscape default palette)?

It take few second to fall into that issue. First opening of menu always work but second one usually fail. There is some very little chance that this will work more then two times. So in short if you would like to use more then two colors, Inkscape is completely useless on Ubuntu for last few months...

> And does it happen with any color palette, or with a specific one
Inkscape allow to change color palette? Nice to known. Nerveless I use default settings. I really would like to use Inkscape to draw few colored lines, nothing more.

> Not reproduced on Windows XP
Yes, it is working fine on my computer with windows 7. I'm sure this bug is connected with GTK & Ubuntu...

Did you try to run Inkscape with the overlay scrollbars disabled? Open a terminal window, and launch inkscape like this:

$ LIBOVERLAY_SCROLLBAR=0 inkscape

... or without the global menu bar (also Ubuntu-specific):

$ UBUNTU_MENUPROXY=0 inkscape

Steps to reproduce on Ubuntu:

* First right mouse click on color pallet. Pop-up menu always appear:

* After second and next clicks that menu don't appear at all.

* After several clicks an error appear from screenshot

Disable of overlay scrollbars works !!!!!!!!!!!!
Working command: LIBOVERLAY_SCROLLBAR=0 inkscape

I have check second command with disabling of global menu bar but it don't work.

Just in case: here's a link to instructions how you can add this to the launcher for inkscape:

(disabling the overlay scrollbars also happens to work around another conflict in inkscape which prevents pressure sensitivity to work with tablets on Unity)
