CUPS crashes when lpr a UTF-16LE file
Last modified: 2014-10-03 14:50:47 EDT
Description of problem:
Trying to print a Windows-style UTF-16LE file crashes CUPS; in my case I was printing to a PostScript network (Jetdirect) printer.
Version-Release number of selected component (if applicable):
Steps to Reproduce:
printf '\xef\xbb\xbfHello, World!' | iconv -f UTF-8 -t UTF-16LE | lpr
lpr prints "lpr: Uknown", and the server crashes.
Either an error message, or conversion to a sane format.
lpr: Unsupported format 'application/octet-stream'!
Please attach /etc/cups/cupsd.conf, /etc/cups/printers.conf, and the PPD for your default printer from /etc/cups/ppd/. Thanks.

I haven't been able to reproduce this here. Could you please adjust the 'LogLevel' line in /etc/cups/cupsd.conf to read:
and then run 'service cups restartlog' as root? Then run 'strace -tfp ...' to attach to the cupsd process and capture the syscalls.
Print the UTF-16LE file and when cupsd fails again, please attach the strace log as well as /var/log/cups/error_log.
This message is a reminder that Fedora 10 is nearing its end of life.
Approximately 30 (thirty) days from now Fedora will stop maintaining
and issuing updates for Fedora 10. It is Fedora's policy to close all
bug reports from releases that are no longer maintained. At that time
this bug will be closed as WONTFIX if it remains open with a Fedora
'version' of '10'.
Package Maintainer: If you wish for this bug to remain open because you
plan to fix it in a currently maintained version, simply change the 'version'
to a later Fedora version prior to Fedora 10's end of life.
Bug Reporter: Thank you for reporting this issue and we are sorry that
we may not be able to fix it before Fedora 10 is end of life. If you
would still like to see this bug fixed and are able to reproduce it
against a later version of Fedora please change the 'version' of this
bug to the applicable version. If you are unable to change the version,
please add a comment here and someone will do it for you.
Although we aim to fix as many bugs as possible during every release's
lifetime, sometimes those efforts are overtaken by events. Often a
more recent Fedora release includes newer upstream software that fixes
bugs or makes them obsolete.
The process we are following is described here:
Fedora 10 changed to end-of-life (EOL) status on 2009-12-17. Fedora 10 is
no longer maintained, which means that it will not receive any further
security or bug fix updates. As a result we are closing this bug.
If you can reproduce this bug against a currently maintained version of
Fedora please feel free to reopen this bug against that version.
Thank you for reporting this bug and we are sorry it could not be fixed.
This bug is long since obsolete.
