DockbarX 0.90.2 cannot handle chromium webapps correctly

[Philipp Specht]

When starting a chromium web app (chromium-browser --app=url), the chromium icon isn't shown. I think it has something to do with the icon dockbarX is trying to show. Here's the debug output:

DockbarX 0.90.2

I confirm. Xubuntu 14.04 + XFCE 4.12 - the same behaviour.

Interestingly, if you make a .desktop file that contains the chromium-browser --app command and attempt to drag/pin it to the dockbar, you get a different traceback like this:

| Traceback (most recent call last):
ERROR | 2015-03-08 20:14:51,541 | File "/usr/lib/pymodules/python2.7/dockbarx/dockbar.py", line 124, in do_drag_data_received

ERROR | 2015-03-08 20:14:51,542 | TypeError: translate() takes exactly one argument (2 given)

To fix this, you simply remove "None" from line 1145, and then you can pin chromium apps to the dockbar if you have created a .desktop file for them (I created mine in /usr/share/applications/) and explicitly named the Icon in there with a line like this:

Icon=thunderbird

That however, does not solve the problem above, where after it launches, it fails to stay "launched" because it still can't parse the icon string for some reason.
