Acroread Ubuntu problem

[border-rider]

<Govt trashes my computer OMG TFH black helicopters conspiracy>

HMRC uses interactive pdf files for you to submit various returns. Usually this works fine, but it needs Adobe Acrobat Reader v9.n, which I have

This time as I was doing the necessary tweaks to the document's  signature certification acroreader locked up, irrevocably. Kill it and start again, it stays non-responding. So I deleted the offending file, removed acroreader and all its little residual scraps, rebooted, reinstalled it. Rinse & repeat. No better.

What's going on ? I can only guess that somewhere there's a sneaky security configuration file that's, cockroach like, surviving the thing being nuked from orbit.  Anyone got any idea where it might be ?

Ubuntu 11.04 64 bit.

Any clues from

Code: [Select]

lsof | grep acroread?

You can see every file that the process opens, as well as those it fails to open, by running:

strace -etrace=open acroread somefile.pdf

I waved both those commands at it, learned a bit (especially from Phil's) and then lo ! it worketh with no human intervention.

Thanks, chaps; you have magic hands.
