Comment (by tch):

 Ok, going deeper, found that the crash is caused by something at

 sugar-toolkit-gtk3/src/sugar3/sugar-fatattr.c
 "fprintf(stdout, "Error %s attributes: %s\n", verb, strerror(errno));"

 errno returns 25, but strerror(25) returns garbage string...

 While I was reading about this, saw that strerror is not thread-safe, and
 switched to strerror_r. This stops sugar from crashing, but does not solve
 the garbage string issue.
