[Pkg-cups-devel] Bug#489045: Bug#489045: cups: infinite loop, 100%CPU use, while trying to print with HPJetDirect

[Patricio Rojo]

Attaching requested info, thanks!

=================
error_log:  (the first two entries appeared when adding the printer
through the web interface, even though the printer appeared to be
successfully added with no error messages in the web interface.  The
last entry appeared only after I 'kill -9' the runaway process)

strace.out  (I ran it for 10 seconds and I got a file with more than
800000 lines that seem to repeat the following forever)
