This sounds rather like what I am experiencing, tbough not identical. I am using vim-7.3 in xmonad. If I start gvim from a terminal it locks up, and I get these messages: ------------------------------------------------------------------------------------ E852: The child process failed to start the GUI [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. gvim: ../../src/xcb_io.c:273: poll_for_event: Assertion `!xcb_xlib_threads_sequence_lost' failed. ---------------------------------------------------------------------------- It doesn't happen with other window managers. I'm using gvim -f as a workround. Apologies if I'm off-track here; I found this thread when googling for the above error. Vim: Caught deadly signal ABRT Press ENTER or type command to continueVim: Finished. -- You received this message from the "vim_dev" maillist. Do not top-post!
