Freezes when opening URL while browser is not started
Bug description
Gajim waits until the process terminates. Unless then, Gajim's windows won't redraw.
Steps to reproduce
Close your browser.
Click an URL in any conversation.
Try to return to Gajim windows while leaving browser window to run.
In the code, I see that the same would happen with email URIs, and so on.
Software versions
OS version: up-to-date Gentoo
