Thank you fot the bug report, Sebastian.

I have reverted the patch for #19632, so this shoueld work again. The fix will be included in the next GNU gv release.

Hi Sebastian,

you're right, it is not fine that error messages are supressed.
The problem is: How to differentiate betwenn warnings and errors?
Any suggestions?

Wed 07 May 2008 10:29:53 PM UTC, original submission:  

If I open a file with gv (as a command line argument, or opened via File menu), there is no error message if gs cannot render the file. Instead, gv simply shows an empty page.

To test:

gv /bin/ls


Some sort of error message that /bin/ls is not a valid Postscript file.

Actual behavior:

gv shows an empty page.

This can be rather confusing, as an invalid PS file is not the same as an empty one.


Old versions of gv used to display an error message in this case.
This was apparently changed by the patch for  #19632, "quiet and .gv watch settings are not respected".

This patch seems to suppress all popup messages if option -quiet is set, even error messages from gs. This seems incorrect to me, as the manpage only says that -quiet causes gs to be called with -dQUIET. It says nothing about suppressing all error messages.

If gv is called with -noquiet, opening an invalid file causes an error popup, as expected. However, -quiet seems to be the default for gv, hence the observed behaviour.
