Description Nick Leverton 2015-10-08 08:53:23 UTC
Okular  crashes every time on the following .ppt file:

http://www.denx.de/wiki/pub/ELDKHistory/DocumentationLinks/OpenEmbeddedv1.ppt

I assume okular is meant to handle .ppt's since it has registered itself as a handler in "file associations".

Reproducible: Always

Comment 1 Justin Zobel 2022-11-10 22:32:51 UTC
Thank you for reporting this issue in KDE software. As it has been a while since this issue was reported, can we please ask you to see if you can reproduce the issue with a recent software version?

If you can reproduce the issue, please change the status to "REPORTED" when replying. Thank you!

Hi,

Thankyou for taking the trouble to check back on this report.  The original URL is dead unfortunately and I can't find a copy of that file on the net.  However I have tested with a different ppt and unfortunately I am still seeing a segfault on opening.

Application: Okular (okular), signal: Segmentation fault
