incorrect transformation of man: link in run dialog

[Ivan Koznacheev]

Binary package hint: gnome-panel

gnome-help (aka yelp) uses man: link in man:*** format, where *** is manpage name.

gnome-panel run dialog (Alt-F2-dialog) transforms such links in format man:///*** and yelp displays error message (something like "address man:///*** is invalid", I use non-english version so I don't know exact english message text)

analysing nature of this transformation I found such call stack:
panel_run_dialog_execute in panel-run-dialog.c
panel_util_get_file_optional_homedir in panel-util.c
g_file_new_for_uri from glib-2.0/gio/gfile.h
last function makes gfile with address man:///*** from location in format man:***

currently I've patched my gnome-panel by adding some lines of code in panel_run_dialog_execute:

before patching:
 file = panel_util_get_file_optional_homedir (command);
 url = g_file_get_uri (file);
 scheme = g_file_get_uri_scheme (file);
 g_object_unref (file);

after patching:
 file = panel_util_get_file_optional_homedir (command);
 url = g_file_get_uri (file);
 scheme = g_file_get_uri_scheme (file);
 if (strcmp(scheme,"man")==0)
 {
     strcpy(url,command);
 }
 g_object_unref (file);

now man:*** works fine for me, but I'm afraid of memory leaks or buffer overflow (I'm not programmer)

Changing gnome-help code in order gnome-help to take both format of man: links would be better solution.

Sorry my poor English and sorry also if I put this bug in wrong place.

I can confirm the issue. Please note that this bug did not exist in gutsy, and doesn't exist in Debian testing (Gnome 2.22 I believe). It's just Hardy.

Whoops - meant to mention that 'gnome-open man:ls' works - it's just that run dialog box as far as I can see.

Confirmed in up-to-date Hardy. 'gnome-open man:ls' behaves correctly.

I'm confirming this bug based on the comments from the last two reporters as well as myself. I can reproduce this in Hardy Heron, Version 8.04.01 anytime using Alt-F2, type in "man:page-wanted". Thank you for helping to improve Ubuntu.

This is still valid using Ubuntu Lucid Beta1 image, dated 2010-03-17.1. In a terminal, 'man ls' works as expected to display the manual page. Hitting Alt+F2, typing 'man ls' fails silently with no error and no other dialog. Hitting Alt+F2, typing 'man:ls' gives an error box, "Unable to load page", "The requested URI "man:///ls" is invalid". Clicking on 'OK' results in a blank Help Browser window.
