[Bug-AUCTeX] 11.85; PDF file deleted when generating previews

Following a bug report that I received and my attempts to diagnose theissue, I'd like to report two issues with Preview mode:

- In AUCTeX (latest release) with PDF mode on, using the command boundto the menu item "(or toggle) at point", the .pdf file associated withthe master file for the current .tex source is deleted. This isannoying; among the problems it causes is the reported one quoted below.

It appears that the .pdf file is deleted towards the end of thepreview generation; this is noticeable when running the slower"generate previews for buffer".

Further investigation shows that the .pdf file is deleted by preview-gs-sentinel because it is the car of `preview-ps-file'.

- The user also reports that the PDF viewing application shows a lotof formulas for him (rather than the actual doc); I don't quiteunderstand what's going on. I have verified that Preview generates_region_.pdf rather han anything else.

I hope this was sufficiently detailed; ask if I can supply more info.

Maybe this will give more clues... (It may be messed up even more.)

I had  a pdf preview of a paper opened by Skim.
I toggled the preview of a formula in the file to its latex code(command-click) without making any change.
Then I run preview for the document (just to avoid preview at point).
Skim gave me all formulas from the paper, centered one under another,
in a very long file. No text.

Right. Turns out that "Toggle Preview at Point" actually deletesthe main PDF file. That doesn't make sense to me.
Jan, do you want to take it up with the AUCTeX Help group then?It's their code.

I suspect (since it makes sense) that preview generates a new pdffile at each invocation - even if it has the same name. In thiscase, skim's behaviour is as expected.

OK, I reproduce the behavior. I see that the .pdf is correctlygenerated with a new time stamp. I did get correct Skim behaviorthe first time around, but not after using "generate preview atpoint". It's unclear to me what the interaction with AUCTeX/previewis, but I would say that as soon as the PDF is regenerated, Skimshould update. (After doing a "revert" in Skim, things work fine.)
I can imagine that Skim looses the handle on the file. Maybe (!)Aquamacs/AUCTeX deletes the .pdf or does something else to it, andthe file system can't keep track of it. Something like that perhaps.
Thus, I defer to the Skim team for now!
PS., Christiaan, the Report Bug link on the Skim website links tothe main Sourceforge homepage or their login screen.

Jan / Daniel,
If this did not change with a Skim version change, then pleaselet us know which version of Aquamacs/Emacs you're using exactly,and make sure that this problem replicates when (in Aquamacs) youstart without customizations (Help -> Diagnose -> Startwithout...).
If we can replicate the bug, we'll be happy to help of course.

Jan,

I observed the same behavior in the previous version of Skim, too.

I have to close Skim's preview file and generate a new one.
I have observed this annoying behavior syncing with the newestSkim 1.2.1,
I do not know whether it was present in earlier versions.

Remember to cover the basics.  Including a minimal LaTeX example
file exhibiting the problem might help.
