After upgrading from Ubuntu 11.04 to 11.10 and Okular seems to be not working properly. When I open a pdf document, it says 'Reloading the document ...' again and again and an hour glass is shown. The problem is intermittent and happened with the following pdf. Has anyone had similar experience?

can you add an example weblink to a pdf that you say produces this issue? – fossfreedom Nov 10 '11 at 9:24
It happens with this pdf. BTW, is doesn't happen now. – Praveen Sripati Nov 10 '11 at 9:41
Are you saying that the problem is intermittent? Don't forget to add the link info and the answer to this comment back into your question. – fossfreedom Nov 10 '11 at 9:51
yes - intermittent. Will do. – Praveen Sripati Nov 10 '11 at 9:56
sounds like a bug of some-sort. Have you attempted to pin it down e.g. is it a size issue? Does it occur with PDFs with form-fields etc etc. Does this occur with "evince" or "acroread"? – fossfreedom Nov 10 '11 at 10:16

I downloaded your pdf and I can confirm that Okular has no problems opening it. However, there's a nice feature in Okular that makes it to reload a document whenever the file on disk is changed.

You can reproduce this by opening a terminal window and issuing

touch filename.pdf

while the same file is open in Okular. Or even

 while [ true ]; do touch filename.pdf; sleep 3; done

this will cause Okular to reload the document repeatedly.

I'm not quite sure what was "touching" the file in your case - do you have this file synced with Ubuntu One or Dropbox? Maybe some backup program?

However, the power of KDE is in the amount of knobs programs have :) If it ever bothers you again, go to Settings - Configure Okular - General and un-tick "Reload document on file change"

In you're curious, you can install inotify-tools package which contains command-line tools to monitor file modification messages from kernel's inotify module. You can monitor file change notifications with

inotifywait -m filename.pdf

The pdf is in DropBox, but I hardly change it. – Praveen Sripati Nov 16 '11 at 11:20
Well, then Dropbox is my main suspect – Sergey Nov 16 '11 at 20:58
