Frequently freezes with the error message in the "~/.cache/lxsession/LXDE/run.log" indicating a multi-threading bug:

pcmanfm
[xcb] Unknown sequence number while processing queue
[xcb] Most likely this is a multi-threaded client and XInitThreads has not been called
[xcb] Aborting, sorry about that.

Same error here (1-2 times per hour) when clicking on a file or a folder. PCManFM freezes and process has to be killed via Task-Manager.
PCManFM 1.3.1
on ArchLinux 64-bit
with LXDE

There's downstream bug for this. There are other GTK2 apps that suffer the same fate. Two of them have GTK3 support and upon using GTK3, the problems stop occurring. So the problem seems somehow related to GTK2. However, 1.2 seemed to have no problems. That said, I'm not sure if the problem should be here or with GTK???
