Bug Description

Runnin 2.1.6 Portable Win 8.1 + Office 2013 + Libre

I imported one .ppt file and sent it to live, a traceback appeared:

I was able to re-produce it with the same file few times but then it started working after some restarts and other files in between. I don’t have the permission to share this file but here’s some tracebacks:

I tried to use that presentation nevertheless and other tracebacks appeared:

The problem is most likely that the loading of that presentation failed. Was there any special content in the presentation?

The other thing that I have seen, there is a bug reported somewhere, is that OpenLP choaks when powerpoint shows a dialog window, for example when powerpoint hasn't been used before.

Changed in openlp:
importance: Undecided → Low

There has been quite a few support requests from users experiencing the "object has no attribute 'slidenumber'" traceback, so we should probably try to fix this. As I see it there are (at least) 2 things that could cause this:
1. Loading of the presentation failed, so PowerpointDocument wasen't initilized properly
2. The presentation was loaded by Impress, creating an ImpressDocument, which causes issues when trying to start this with PowerPoint.
