Crash on incorrect file

[GitHubRulesOK]

if a file, folder, sub-folder or zip contains a file with incorrect type (any of these 4 cases)
quickviewer will crash where other apps report incorrect file type

as an example I tried opening a folder that contained sample.pdf that was incorrectly named as sample.png

Thank you for your report.

This problem will be fixed on next release.

I am impressed at the speed with which you resolve issues
I was unable to run versions 0.8 due to hardware issues (intel mobile drivers on touchscreen)
However 0.9 is generally stable except for these odd files which took a while to spot the cause as there was no warning. I had to move files around and use a binary chop to find the offending file.

Improved behavior in 32 bit environment with v0.8.9, and stopped using OpenGL in v0.9.3. With these changes QuickViewer had begun running more consistently on your PC.

A retry was implemented when the image was not able to be read correctly by v0.8.9 correction, but it caused a stack overflow because it is a recursive call.

This issue will not occur in the next release as we set an upper limit for retries.
