​I took a quick look at the source where I _think_ the message is coming
from: src/main/util.c . That message comes out when the chdir() function (C
library routine) returns any kind of error.​ Because you said that have
read & write access (you should also have execute in most cases), then the
only return which makes sense is ENAMETOOLONG (although it could also be
ENOMEM). How long is the path name? The usual limit is 255 bytes.
