kdesu works fine most of the time. Sometimes, after restarting X, kdesu fails to work, it just hangs. Running strace shows that it hangs when connecting to the user's socket file in /tmp. Deleting that socket file restores functionality. Reproducible: Sometimes Steps to Reproduce: 1. Restart X 2. Run "kdesu <command>" 3. Repeat until step 2 fails. Actual Results: kdesu hangs. Expected Results: kdesu runs the command.

Created attachment 219051 [details] strace of kdesu running konsole
Hasn't happened in 4.3.5 yet on either machine so fingers crossed...
Alas, it didn't just go away by itself after all. Does the socket 'go stale' or is kdesu forgetting to delete it after it has finished with it?
Does this still happen with kdesu-4.4.4?
(In reply to comment #4) > Does this still happen with kdesu-4.4.4? > By strace-ing kdesu on my machine, I have figured out a socket problem: removing /tmp/ksocket-mike/kdesud_:0 works for me. This is the output of kdesu -c /usr/bin/konsole on my machine getuid() = 1000 stat("/tmp/ksocket-mike", {st_mode=S_IFDIR|0700, st_size=384, ...}) = 0 lstat("/tmp", {st_mode=S_IFDIR|S_ISVTX|0777, st_size=1280, ...}) = 0 lstat("/tmp/ksocket-mike", {st_mode=S_IFDIR|0700, st_size=384, ...}) = 0 lstat("/tmp", {st_mode=S_IFDIR|S_ISVTX|0777, st_size=1280, ...}) = 0 lstat("/tmp/ksocket-mike", {st_mode=S_IFDIR|0700, st_size=384, ...}) = 0 stat("/tmp/ksocket-mike/", {st_mode=S_IFDIR|0700, st_size=384, ...}) = 0 access("/tmp/ksocket-mike/kdesud_:0", R_OK|W_OK) = 0 socket(PF_FILE, SOCK_STREAM, 0) = 9 connect(9, {sa_family=AF_FILE, path="/tmp/ksocket-mike/kdesud_:0"}, 29) = ? ERESTARTSYS (To be restarted)
This still happens to me with kdesu-4.5.1.
someone report upstream plz
Do you have any better luck with kde-4.6.2 (in tree in a few days, stable candidate)?
I just installed 4.6.2, so now it's wait and see if it still happens.
Added upstream bug. Not a regression compared to 4.4, so not blocking stabilization. Jeremy, if the problem occurs again, upstream is asking for a gdb backtrace of the hanging process... this may take some fiddling...
I haven't noticed the bug since I installed 4.6.2, so I'm going to mark it closed.
