[Pkg-xfce-devel] Bug#507197: libxfcegui4-4: Error-hiding is preventing me from debugging a problem.

[J Phelps]

Package: libxfcegui4-4
Version: 4.4.2-4
Severity: normal
Tags: patch


The following unhelpful error message was traced to code in
libxcfegui4-4:

(xfce4-menu-plugin:3979): libxfcegui4-WARNING **: XfceAppMenuItem: unable to spawn xfrun4

This message is generated in the function _command_activate_cb, in the file
xfce-apmenuitem.c, in response to any failure from the function
xfce_exec_on_screen. No attempt is made to retrieve a system-level error
message, nor is any attempt made to retrieve an error code from underlying
libraries.

xfce_exec_on_screen takes an error buffer of the type used by the glib
library as its last argument, but _command_activate_cb passes a NULL
pointer, thereby losing any opportunity to recover error information from
the underlying library.

I'm including a patch to make the library include whatever error information
the underlying library provides in its error message. Perhaps next time
I have trouble, I'll be able to do something better than restarting XFCE4
and all my other applications.
