Comment 6 for bug 1332385

The same annoying bug appears on Linux Mint 17 (based on Ubuntu 14.04) with xfce4-panel 4.11.0-0ubuntu1 too.
But in opposite Wine does appear neither on the Whisker nor the xfdesktop menu ($ xfdesktop --menu) but in the application finder (alt+F3).
The underlying xfce4-applications.menu lists all Wine entries under "Other" but links them somehow with the category "Wine". But at this point my understanding of tree structure here and category structure there stops. If anybody could point out a good resource how the mentioned programs operate I would greatly appreciate it.
