Description Milko Krachounov 2015-02-02 20:12:15 UTC 
After upgrading to Inkscape 0.91, the colour palette is now unusable with QtCurve. A rogue window appears instead of a tooltip, and after closing it, Inkscape crashes. The problem doesn't happen with other styles (such as Oxygen-GTK, Adwaita, Redmond and Raleigh).

I am using gtk2-engines-qtcurve version 1.8.16-2 (Debian) and Inkscape version 0.91-1 (Debian)

The problem has also been reported by other parties to happen with Arch Linux:
https://bugs.archlinux.org/task/43631

Someone has posted a screenshot of the rogue window in this bug:
https://github.com/QtCurve/qtcurve-gtk2/issues/3

Reproducible: Always

Steps to Reproduce:
1. Set QtCurve as GTK+ theme
2. Open Inkscape 0.91
3. Hover the mouse over a colour in the palette

Actual Results:  
A window with no title and contents appears, Inkscape segfaults when the window is closed.

Expected Results:  
A tooltip with hexadecimal colour appears

I am sorry, I forgot to include the output of Inkscape:

Additionally, this seems to be unrelated to the QtCurve preset chosen, because I tried few.
