Issue 165: Java apps cause xmonad to segfault (X11 FFI issue?) http://code.google.com/p/xmonad/issues/detail?id=165 Comment #1 by byorgey: I've now confirmed that this only happens when UrgencyHooks are enabled. Minimal config => no crash. minimal config + UrgencyHooks => crash. my normal config with tons of extensions => crash. my normal config minus UrgencyHooks => no crash. Looks like this is indeed the same issue as #140. -- You received this message because you are listed in the owner or CC fields of this issue, or because you starred this issue.
