buzzed shell while running external editors

Hello everybody.

   I'm trying to use gqview on mac os x tiger, v10.4.2. Everything  
seems to work properly except of extenal editors handling. When I run  
jpegtran as an editor (like it is configured by default), gqview  
executes the command, the jpegtran does its job, but does not return  
control to gqview back, I see the grey "close" button and gqview  
thinks that the external editor is still running.

   I've managed to make some investigation. In src/editors.c gqview  
runs external editors via execvp() function through the shell  
specified in COMMAND_SHELL. Using /bin/ps I see that when the editor  
finishes executing, the shell still remains running.

ryzh@pear:~>ps | grep gqview
15384  p8  R+     0:13.42 gqview .

ryzh@pear:~>ps auxwj | grep 15384
ryzh     15385   0.0  0,0        0      0  p8  Z+    1jan70   0:00.00  
15384 15384 210e9e0    1 (bash)

   I've tried to change COMMAND_SHELL from 'sh' to '/bin/bash', but  
in vain. I've tried to run the command using execvp() directly  
(simply removing the first 2 elements of argv[] array), but the  
dialog window just does not show. I'm not a C programmer, so I just  
don't know how to fix such issue. I've tried gqview 2.0.1, 2.1.1 and  
version from CVS.

   I've googled and searched the mailing list archives, but it seems  
that nobody experienced such problem before :( I will appreciate any  
help or advice.

   Thanks in advance.
