[Pkg-samba-maint] Bug#622673: panic-action segfault involving _spoolss_EnumPrinters

[Joshua Kwan]

Package: samba
Version: 2:3.5.8~dfsg-1

I'm seeing a Samba panic-action a couple times a day, just starting
recently. It appears to come from a computer running Windows 7. This
backtrace was generated after I installed samba-dbg and restarted smbd
but it doesn't look like any extra information was provided as a result.

Like the other poster, the core was not present in the given directory
after the crash occurred.
