seamonkey 2.0.13 does not start, missing libxpcom.so and libxpcom_core.so (Natty, x86_64)

Also tried this :

$ sudo rm /usr/lib/seamonkey-2.0.13/components/libsuite.so

removed also /usr/lib/seamonkey-2.0.13/components/libdbusservice.so
then seamonkey started seemingly fine, but crashed in libspellchecker.so very soon
removed /usr/lib/seamonkey-2.0.13/components/libspellchecker.so , and seamonkey works more stable afterwards (including Mail&NewsGroups)

But for Ubuntu package, these manual interventions are IMO undesirable anyway.

Thank you for reporting this to Ubuntu. This works fine for me on Natty 64 bit. Could you please try reinstalling the package? I don't see anything obviously wrong based on the output provided. If you're still having an issue, could you please provide the output of:
ldd /usr/lib/seamonkey-2.0.13/seamonkey-2.0-bin

Also, please make sure that 'which seamonkey' shows /usr/bin/seamonkey and not another one.

I'm seeing this as well, under the latest Natty updates as of 16-Apr-2011.

This was a new install on a new machine, so there isn't any prior config files hanging around.

Curiously, the --version option doesn't have this problem, and correctly report the version string:

$ seamonkey --version

Other things:

$ which seamonkey

Same problem as of latest Natty right now.

Same problem in Kubuntu after latest Natty updates

The fact that ldd /usr/lib/seamonkey-2.0.13/components/libsuite.so can't find libxpcom.so is a red herring; that library lives in /usr/lib/seamonkey-2.0.13 which isn't in the normal library path, and ldd shows the same result even on a system where seamonkey is working.

I ran LD_DEBUG=all seamonkey and captured the output (see attachment). It shows NS_GetServiceManager is found in libxpcom.so when libimgicon.so is loaded, but for some reason when libsuite.so is loaded, libxpcom.so is never even searched.

Same problem in Xubuntu; have checked this morning after updates, and Seamonkey still not launching windows when clicking on menu entry.

My workround is to use the 2.0.14 binary package from mozilla for now with a manual .desktop file in ~/.local/share

Same here with Kubuntu 11.04 (x64) but I think the problem is universal and independent from Ubuntu flavour.

I have same config as Vogon Zarniwoop and had an issue with libxpcom.so but when using eclipse.
I manage to fix it. See my post at https://bugs.launchpad.net/ubuntu/+source/eclipse/+bug/749698
