Yes I should at least be running a newer version. But you know.. every time I update slic3r, something I need breaks completely :P\r\n\r\nSo I've been happily slic1ng away and then now I tried to run slic3r from the console and I get the following output. The main application window does appear, but then it aborts.\r\n\r\nThe Pango warning appears every time and I ignore it. The other stuff is new. It's possible that I've upgraded some packages since the last time it worked. I don't expect you to fix this on an old experimental version, I just think the bug report may be useful, since it's probably not a change in slic3r but in some other part of the system.\r\n\r\n--------8<--------8<--------8<--------8<--------\r\n\r\n(slic3r:8087): Pango-WARNING **: /usr/lib/pango/1.6.0/modules/pango-basic-fc.so: cannot open shared object file: No such file or directory\r\n[xcb] Unknown request in queue while dequeuing\r\n[xcb] Most likely this is a multi-threaded client and XInitThreads has not been called\r\n[xcb] Aborting, sorry about that.\r\nslic3r: xcb_io.c:179: dequeue_pending_request: Assertion `!xcb_xlib_unknown_req_in_deq' failed.\r\n"},"comment":{"url":"https://api.github.com/repos/alexrj/Slic3r/issues/comments/113993213","html_url":"https://github.com/alexrj/Slic3r/issues/2938#issuecomment-113993213","issue_url":"https://api.github.com/repos/alexrj/Slic3r/issues/2938","id":113993213,"user":{"login":"darrenfreeman","id":4440028,"avatar_url":"https://avatars.githubusercontent.com/u/4440028?v=3","gravatar_id":"","url":"https://api.github.com/users/darrenfreeman","html_url":"https://github.com/darrenfreeman","followers_url":"https://api.github.com/users/darrenfreeman/followers","following_url":"https://api.github.com/users/darrenfreeman/following{/other_user}","gists_url":"https://api.github.com/users/darrenfreeman/gists{/gist_id}","starred_url":"https://api.github.com/users/darrenfreeman/starred{/owner}{/repo}","subscriptions_url":"https://api.github.com/users/darrenfreeman/subscriptions","organizations_url":"https://api.github.com/users/darrenfreeman/orgs","repos_url":"https://api.github.com/users/darrenfreeman/repos","events_url":"https://api.github.com/users/darrenfreeman/events{/privacy}","received_events_url":"https://api.github.com/users/darrenfreeman/received_events","type":"User","site_admin":false},"created_at":"2015-06-22T03:33:22Z","updated_at":"2015-06-22T03:33:22Z","body":"http://flavio.tordini.org/forums/topic/segfault-on-linux\r\n\r\n(might be relevant)"}}
