Segfaults if launched while another instance is running

[wjt]

I installed SparkleShare, and ran it. I attempted to configure a GitLab repository with no success, and quit (I thought) SparkleShare. Then I tried to run it again – it segfaulted. Backtrace below.

I noticed with ps that the first instance is running, although there's no visible sign of it. (I have TopIcons extension installed.) If I kill that instance, I can launch a new instance without a segfault, though no UI is displayed.
