OpenLP freezes when double clicking an image in media manager

[John Cegalis]

Win7 and Linux Mint nightly builds.
In Mint, if I double click an image in the media side, the program will freeze and crash.
In Win7, sometimes I have to double click or single click an image and the program will freeze and crash.
On Win7, sometimes if I hold the Ctrl button to select multiple images OpenLP will freeze and crash.

I attached the Mint debug log and will get the Win7 log attached next.

Win7 log.

I can't reproduce this. Do you have some special settings?

[John Cegalis (jseagull1)]

I attached the settings I have. I can reproduce it every time and it sure does get frustrating.

I've managed to reproduce a temporary freeze on windows, when previewing or going live with an image already in the mediamanager on startup. The image does show after a few seconds. OpenLPs memory use goes up during the freeze, and my log shows that the imagemanager is blocking (loading the image into the mediamanager) for about 5 sec. So this is probably an issue with the imagemanager...

How big is the image-files you are trying to view? The crash you experience could be OpenLP running out of memory.

I tested it with a 75kb image and a 650kb image with the same results. In Mint, a double click is all it takes on an image and it freezes. Checking memory usage for OpenLP shows it is frozen in place, even after a minute of checking it.

After opening:
CPU usage is 4.0% Memory is 2359096 kB

Display a song from Service Manager:
CPU usage is 2.0% Memory is 2400132 kB

Double click an image in Media Manager and freeze:
CPU usage 4.6% Memory is 2464968 kB

I just noticed that if I double click on anything in the media manager, Custom or a song, it freezes.
Linux Mint. I don't have access to the Windows computer at this time to test it.

It seems to do it consistently as soon as I open OpenLP and double click on something in the Media Manager. If I single click or right click on something first, in the Service Manager or Media Manager, it's a lot harder to make it happen if at all.

This and #1413324 may well be the same bug. I've now inadvertently hit it three times at Church, fortunately pre-service, although I'm getting good at saving as I go along now. (Serves me right for using beta software!)
Fortunately my operators are better at avoiding this than me.

Ah! It only triggers when "click to preview" is active. If I have that turned off, then the bug doesn't trigger.

[Raoul Snyman (raoul-snyman)]

Right, narrowed it down further. You need "Double-click to send items straight to live" UNCHECKED, and "Preview items when clicked in Media Manager" CHECKED.

My guess is that the double-click does a double-preview.
