Can't start firefox with Xpra

Priority: major Milestone:
Component: server Version: 0.2.0
Keywords: Cc:



when trying to start Firefox with Xpra it seems that the application starts, but nothing appears on the clients.

The server outputs the following:

Hah, good catch.
It's the gtk3 compatibility code that is causing this, the real exception (which is not shown...) is:

error reading initial property _NET_WM_ICON

It happens because of StringIO - whatever the new io.StringIO does different from the old StringIO.StringIO..

r649 prevents this error from making xpra not manage the window, it just continues without the icon.
The root cause is unclear and I would rather not revert the StringIO change so this ticket should stay open until I can fix this:
