apply start-process fails because of invalid current directory

[Pascal Quesseveur]

Hello,

>From time to time i encounter problems with commands running
start-process for ex. eimp-start-process. Trace follows:

--8<---------------cut here---------------start------------->8---
Debugger entered--Lisp error: (file-error "Setting current directory"
  "no such file or directory" "y:/")
   start-process("eimp-5468Kgf" nil "mogrify" "-resize" "66%"
   "c:/Users/pascalq/AppData/Local/Temp/eimp-5468x-x")
  apply(start-process "eimp-5468Kgf" nil "mogrify" ("-resize" "66%"
  "c:/Users/pascalq/AppData/Local/Temp/eimp-5468x-x"))
...
--8<---------------cut here---------------end--------------->8---


Problem occurs on Windows. Directory y:/ was a removable device
which is no more connected. I have read/written to that directory
before calling start-process. When I connect the device again
start-process runs fine. I have looked through apropos-value for y:/
but I don't see anything valuable.
