If I open a directory in Sublime using the command line (subl path/to/my/folder/), Sublime will open two instances: one with the directory I asked for, and another one with the directory I opened last time I used Sublime. Any idea why ?
I don’t know if it’s revelant, but the problem occurs with Ubuntu 12.04.
You are most likely using Sublime’s save last session feature.
You can disable it:
