Thunderbird with CIFS mounted home directory [SOLVED]

[kazakhan]

After many years procrastinating I've finally had a crack at building a single login with roaming profiles. It's been bit of a nightmare but finally almost all is working well. I'm using openldap with pam_mount for authentication and pam_mount also mounts a users home directory from the server and the clients use kdm\kde. I haven't tested every application thoroughly yet but it seems everything except for Thunderbird & Kmail is working fine. File permissions etc all seem correct and I'm unable to work out or find a solution anywhere as to why Thunderbird & Kmail refuse to load (they both seg fault with\without a profile setup).
I'm using the following to mount the users home directory which is the only change made.
/etc/security/pam_mount.conf.xml

You state that the program "seg faults". Do you mean specifically that it is dying from signal 11, SIGSEGV ("Segmentation fault") or just that the program dies unexpectedly? If a core file is produced, please post a backtrace. You probably need to read and follow the instructions in How to get meaningful backtraces in Gentoo first.

If you mount some other networked filesystem on the home directory, do you encounter problems? If you manually mount the CIFS volume on the home directory, rather than letting PAM do it, do you encounter problems?
