Are there any particular circumstances that this occurs?

[CageFox]

No, just randomly. It shows raw blue screen instead of photo and when I try to see my desktop back the error window appears

[marijnkampf]

Which version of Windows are you running?

[CageFox]

Windows 8 64bit

[CageFox]

Is there any way to find which of my thousands pictures causes the error? May be some debug log "showing picture .1.. ok\nshowing picture ..2. ok"
?

[marijnkampf]

Yes there is:

• In the RPS Configuration screen (Press S whilst screensaver is running or Right click desktop > Personalize > Screen Saver > Settings...)
• Select Slideshow tab
• Show advanced settings...
• Check Debug log

If you identify particular images / files that cause a crash I would really appreciate it if you would be able to post (a selection of) them to GitHub or email ( see http://www.abscreensavers.com/contact ), so I can create a fix for RPS.

[CageFox]

Ok. And where is this debug log location?

[CageFox]

BTW. This exception unhandled, but you can handle it and display informative message on the screen ;)

[marijnkampf]

Next to the Check Debug log checkbox there is a button "Open log location in Explorer". Typically this is C:\users[user name]\AppData\Local\Random Photo Screensaver\debug_#date#.txt.

BTW That is why I'm hoping you can send me a sample file so I can fix the issue :)

[CageFox]

Ok. Thou the sample picture may contain very explicit content ;)

[marijnkampf]

Please keep it PG rated on GitHub, if the explicit content are the only ones causing a crash please use email address from contact page :/

[CageFox]

The trouble image not appears in the debug log. Last image in the log is ok, and then screensaver falling in blue screen without record in log
So, I still unable to detect one

[marijnkampf]

The debug log is written before the file is accessed so it should have written it before it crashed. It could be that the issue isn't a particular file as I expected. Would you either be able to run RPS on a subset of images and keep removing images until it crashes or navigate through your images in RPS using the shortcuts and seeing whether it crashes on a particular image?

[CageFox]

No, this not possible. I've got about 8000 pictures, it will take too long time to find buggy one. May be you can add some debug code and may be send me debug version with extended trace of exception stack?

[marijnkampf]

Fair enough, I've opened a separate issue to for adding a global exception catch #49

I'll let you know when it's available.
