"Could not initialize the application's security component" seen when starting Lotus Notes 8.5.2 on Ubuntu Linux 10.10

Hmmm, for no obvious reason, I started seeing this message, in a screen-obscuring dialogue box, when starting Notes 8.5.2 on Ubuntu Linux 10.10

Could not initialize the application's security component. The most likely cause it problems with files in your application's profile directory.
Please check that this directory has no read/write restrictions and that your hard disk is not full or close to full.
It is recommended that you exit the application and fix the problem.
If you continue to use this session, you might see incorrect application behaviour when accessing security features

as per the screenshot below.

This bug report in Launchpad led me to the solution, suggesting that the problem may be due to a missing or, in my case, incorrectly permissioned, Eclipse subdirectory.

To test this assumption, I ran the following set of commands: -

ll /home/hayd/ | grep mozilla

returns

drwx------  6 hayd hayd      4096 2010-10-11 18:37 .mozilla/

ll /home/hayd/.mozilla/

returns: -

The solution ( for me ) ?

As root ( via sudo bash ), run: -

chown -R hayd:hayd /home/hayd/.mozilla/eclipse/
chmod -R +rwx /home/hayd/.mozilla/eclipse/

These two commands set the appropriate ownership and read/write/execute permissions to the eclipse subdirectory that Notes uses.

This appears to have resolved the problem - so far......
