Return of Bug 2101 - Infinite recursion
« on: March 17, 2016, 09:05:25 PM »
I think this bug has come back.
https://lists.kolabsys.com/pipermail/bugzilla/2013-August/010518.html

[16-Mar-2016 19:08:46 America/New_York] PHP Fatal error:  Maximum function nesting level of '100' reached, aborting! in /usr/share/roundcube/program/lib/Roundcube/rcube_washtml.php on line 291

It appears to happen with e-mails that have attachements.  First one was an e-mail with an HTML attachment.  This one has a PDF attachment.

I can still access / read all other e-mail.  It's just these two (that are the same with the same PDF) and the html message (since deleted using alpine).

Let me know what else I can post to be helpful, or if someone wants me to forward the message in question.

Thanks.

Extra info.  I made an incorrect assumption, it does not have a PDF in it.  Alpine says it contains this:

Parts/Attachments:
   1     OK     ~46 lines  Text
   2.1 Shown   ~145 lines  Text
   2.2          4.8 KB     Image

This has nothing to do with attachments. This is HTML parsing routine. Looks like HTML content may be invalid or just crazy (many nested tags). You can change the nesting limit in php.ini.

We fixed this once to prevent from the fatal error here. What version are you using?

Hmm, thanks for the tip.
I just realized the version I'm using might be a bit old.
Roundcube Webmail 0.9.5

Should I expect this bug to go away when I upgrade?

Thanks.

Yes. It was fixed in 1.0.

Thank you Alec,
sorry for the false report then.
I appreciate your response, and everyone's work on this project.
