If you can't say it, show it.

SUMMARY

First, a disclaimer: this may well have additional parameters as to when it's triggered or what triggers it. What I have tested is my own configuration, because the possible combinations are too many. You'll hopefully understand when you read further.

Now the issue: I use Dolphin in Icons view mode and set the file label to show a maximum of 3 lines of a filename before it crops it; I also have the size of a file shown as an additional line, which becomes the 4th line when the label is at max size.

I noticed that with MKV files, when the part of the filename ("part" as in character sequences separated by spaces) that needs to be cropped is the last one before the extension, then that part will be cropped one character later and the cropped label will actually span 4 lines instead of 3 because the extension part will overflow, with that extra 4th line overlapping the actual 4th line that displays the size.

My attempt at describing this is lame, I know, and pictures speak volumes compared to words in this case, so please take a look at the screenshot. Short explanation:

1) First three files have a filename of "1 - This is a really long name to be tested.XXX"

2) Next three files have a filename of "2 - This is a reeeeeeeeeeeeeeeeeeeeeeeeeeally long name to be tested.XXX"

3) Last three files have a filename of "3 - This is a really long name to be teeeeeeeeeeeeeeeeeested.XXX"

Notice how in the third case, the file with the .mkv extension is exhibiting the issue I'm trying to describe. Also note that all of these files are actually text files with a modified extension, and copies of each other: I just created "1 - This is a really long name to be tested.txt" and duplicated/renamed that as needed. In other words, it obviously doesn't have to be an actual MKV file in order to trigger this.

ADDITIONAL INFO:

I've found this old bug report here from back in the 4.x days that describes the exact same issue, so maybe this is a regression:

https://bugs.kde.org/show_bug.cgi?id=337104

In my case it's not a dot that produces it, but I have also noticed that in other problematic files, when there is a dot in the last part/word of the filename, the cropped label will end in ".....mkv", i.e. 4 dots + .mkv", instead of "....mkv", i.e. 3 dots + .mkv (as it is for pretty much every other extension I've tried).
