Comment 6 for bug 167869

hi, all!

pbaggio's #2 suggestion is precisely what was coded into the Gtkmm preview. If the file is larger than a certain size (I think we used 1MB), then display an inlined svg file that says "Too large for preview". You could likely be able to just copy and paste the code for that. If this problem is with the Gtkmm dialog, then maybe the threshold needs to be lower.
