Nautilus starts with under 300 MB and after thumbnailing some jp2 files (JPEG
2000) memory ends up above 900 MB. Closing all nautilus windows does not
release the memory. Memory is only freed when doing nautilus -q.
The more files is thumbnails the more memory is uses.
Steps to reproduce:
Drop a few jp2 files in a folder (I tested with lossless jpeg2000 files about
3000 by 3000)
Quit nautilus (nautilus -q)
Start nautilus again and open the folder containing jp2 files.
Watch memory go up as nautilus is thumbnailing each file.
Close nautilus (ALT-F4 or clicking in the red cross), memory is never released.
Quit nautilus (nautilus -q) and memory is freed.
Valgrind is very helpful, apparently libpixbufloader-jasper.so is used
to read jp2 files.
