[Bug 339875] [NEW] ksmserver stops answering on the SESSION_MANAGER socket

[fwyzard]

Public bug reported:

Binary package hint: kdebase-workspace

After my KDE4 session has been open for a while (from some minutes to
one hour, it's not clear the exact amount of time needed to trigger the
bug) ksmserver stops answering to non-KDE applications.

I can see a simple example of this behaviour using vim.

ltrace hangs at:

  getenv("SESSION_MANAGER")  = "local/katchoo:/tmp/.ICE-unix/833"...
  IceAddConnectionWatch(0x51f570, 0x82cfa8, 0, 0, 82) = 1
  SmcOpenConnection(0, 0, 1, 0, 15

strace hangs similarily:

  socket(PF_FILE, SOCK_STREAM, 0) = 6
  uname({sys="Linux", node="katchoo", ...}) = 0
  connect(6, {sa_family=AF_FILE, path="/tmp/.ICE-unix/8336"...}, 21) = 0
  fcntl(6, F_SETFD, FD_CLOEXEC) = 0
  write(6, "\0\1\0\0\0\0\0\0"..., 8) = 8
  read(6,


At this point I'm only able to start new applications from a terminal where the SESSION_MANAGER environment variable is not set.
