Comment 34 for bug 346840

Hi,

I am also affected by this bug and I have found a simple workaround that “fixes“ the bug until you close the buddy list:
on any workspace having at least one window open (excluding the buddy list), try to swap pidgin's taskbar icon with another one by drag-and-drop.

Then the bugging taskbar icon will magically disappear from all workspaces where it should not be (until you close and re-open the buddy list)
