pluma goes bonkers with very large file (>40MB)

[Robert Pearson]

I had a Mac. It produced some very large (corrupt files) larger than 40 MB. When I open the file with pluma, the screen goes very dark. I have to switch to Solarized Light just to read the screen. Apparently, the Mac had appended many copies of the file to itself. I cut and pasted the first two copies into new documents (they were not duplicates, but the rest of the file was copies of the second piece).

I then delete all the text and save a 0 byte file.
Then I can see the correct Solarized Light color scheme. Then I can switch back to the Classical color scheme.

I will have to build my own app to split the copies.

In the meantime, please fix the scaling bug in pluma. I have 32GB of RAM. Pluma should not have trouble with a 40MB file.

I know Microsoft Word has problems with files over about 50 MB.
I believe these bugs are due to the false paradigm of "all files are less than 1 MB".
