Bug#292938: speedy-cgi-perl: Running /usr/bin/speedy as non root result in Segmentation fault
Jose, What kind of information do you need ? In the mean time I resolved the problem by adding a root sticky-bit on the executable. (Perhaps it's something the program can't read when run as a non-root user.)

Bug#292938: speedy-cgi-perl: Running /usr/bin/speedy as non root result in Segmentation fault
Jose,
While running the strace I noticed the non-root user could not create the
file in /tmp. Indeed the file permissions on /tmp were 755 in stead of 1777.
I changed the permissions and it works like a charm.
Sven

Please, don't remove CC to the bug #, so BTS can keep track of mails.
Having a backtrace of the executable when it hangs could be interesting.
Also, you could send me directly a strace of it running (os speedy-cgi-perl,
not smokeping)
Thanks,
