This is apparently a race condition, where if slrn gets to run before the parent in luit's fork sets the terminal, tcsetattr() will hang. I have put in a patch to make the child wait on the parent, and filed an upstream bug here: https://bugs.freedesktop.org/show_bug.cgi?id=8490 The fix will appear in xorg-x11-apps-7.1-4.fc6. |
Description of problem: when calling an application with luit for the first time, it works without any problems. when calling the app the second time, it just hangs: [tscherf@tiffy ~]$ LANG=de_DE luit slrn Here is the strace output: [tscherf@tiffy ~]$ strace luit slrn execve("/usr/bin/luit", ["luit", "slrn"], [/* 40 vars */]) = 0 brk(0) = 0x88a1000 mmap2(NULL, 4096, PROT_READ|PROT_WRITE,
