xdg-open fails to process a quoted argument with spaces and splits it instead

There appears to be a workaround for issue #173: use bash -c as a wrapper and pass the last argument (%u in our example) to it as $1 (see this answer for details). Okay, xdg-open has an undocumented limitation noone has thought of in the first place, but we can deal with it.

In theory this would look like this:

[Desktop Entry]
Exec=bash -c 'seamonkey -remote openURL($1,new-tab)' seamonkey-wrapper %u

Here, bash will name the shell seamonkey-wrapper and eventually execute

seamonkey -remote openURL(%u,new-tab)

with %u already expanded by xdg-open.

The specification prescribes that double quotes should be escaped, and whatever is to be quoted should be quoted.

The problem is, I can't get this to work. No matter how exactly I escape and/or quote my arguments:

Exec=bash -c "seamonkey -remote openURL($1,new-tab)" seamonkey-wrapper %u
Exec=bash -c \"seamonkey -remote openURL($1,new-tab)\" seamonkey-wrapper %u
Exec=bash -c 'seamonkey -remote openURL($1,new-tab)' seamonkey-wrapper %u
Exec=bash -c \'seamonkey -remote openURL($1,new-tab)\' seamonkey-wrapper %u

-- I can't pass seamonkey -remote openURL($1,new-tab) as a single quoted argument to bash, w/o xdg-open splitting it into three tokens.
