Bug#931822: xdg-utils: xdg-open fails to open http urls under LXDE

[Victor Wagner]

Package: xdg-utils
Version: 1.1.3-1
Severity: normal

Dear Maintainer,

*** Reporter, please consider answering these questions, where appropriate ***

   * What led up to the situation?

After freshly installinng Debian buster with LXDE desktop
I've found out that many programs such as syncthing, claws-mail, fossil
etc are unable to open HTTP URLs in browser.

Instead of opening browser window they pops up small dialog which reads

file /home/vitus/http://localhost:8384 not found

   * What exactly did you do (or not do) that was effective (or
     ineffective)?

Investigation shows that root of problem is   line 931 in the xdg-open
script:

    if pcmanfm --help >/dev/null 2>&1 -a is_file_url_or_path "$1"; then

Obvoisly it is error in the shell logic, and && should be used instead
of -a. -a works as logical AND operator only in the command line
of test(1) (AKA [ command), not when condition is exit code of arbitrary
unix command.

   * What was the outcome of this action?
Replacing this line with

    if pcmanfm --help >/dev/null 2>&1 && is_file_url_or_path "$1"; then

Fixes the problem.
