Public bug reported:

I happen to have a full archive of playstation home on my hdd (as one does), and here is an example of the file tree: https://gist.github.com/johndrinkwater/f1c84501430e5d35a4af 
It causes baobab to take many many many minutes to process, making the application appear hung, while it seems to be allocating more memory, but in such small increments that is absorbing most of the time:

>From an strace of the process, while it has stopped spinning the processing spinner:
brk(0x3dd8000)                          = 0x3dd8000
brk(0x3df9000)                          = 0x3df9000
brk(0x3e1a000)                          = 0x3e1a000
brk(0x3e3b000)                          = 0x3e3b000
brk(0x3e5c000)                          = 0x3e5c000
brk(0x3e7d000)                          = 0x3e7d000
