12 WOW! A rather large number I would think.

42 Take a pic of it so you have a more precise idea what it reports and google
43 for ideas on what may be causing it. If you're on a console use tee to
44 redirect the output to a file, or use gpm to select some text off the screen
45 and paste it in a file.

53 I have found the file indexer occasionally chews up CPU non-stop. I think I
54 disabled it at some point but in any case I have not noticed it chewing up CPU
55 since. Could it be the file indexer now needs to re-index all your images and
56 it falls over itself due to the number and directory depth?
58 Is possible to drop into a console or ssh into this PC when it's hanging to
59 see what process(es) are taking up resources in real time?

65 Is there a difference in the metadata of these few images compared with the
66 rest in the whole directory?

86 Some ideas in no particular order:
88 Compare the metadata of an image which works without crashing and one that
89 causes a crash, with exif or less. If there is no discernible difference it
90 may be the problem is not with the metadata, but with Plasma being able to
91 parse all these files and their metadata.
93 Gradually add images to find a number at which the problem occurs and back off
94 from there. Not a solution, but a workaround.
96 Another workaround, restructure the fs to have fewer layers, but keep the same
97 large number of images to see if it process them without a crash.
99 Do you really all 100,000 images? Is it worth keeping all of them, or is it
100 perhaps time for some house keeping?
102 Wait for new Plasam version to come out and perhaps report a bug if one is not
103 yet posted.
