[Kumar]

Package: devhelp
Version: 41.2-2
Severity: normal
X-Debbugs-Cc: kumar at onenetbeyond.org

Dear Maintainer,

In Debian Sid, "devhelp" doesn't open a single page i.e. (default) empty
page remained open. I tried to click on different manual and even
reinstall "devhelp" and "cppreference" manual, but issue persists.

### Steps to reproduce
- Open devhelp.
- Click on any reference manual page available in left side of the bar.
    In my case, (by default) I've few (Pango*) manuals.

### Expected output
Corresponding clicked page should be opened.

### Actual output
An (default) empty page remained open.

### Additionals
When "cppreference" manual is installed and devhelp is launched from
terminal, we'll get some extra information.

$ sudo apt install cppreference-doc-en-html  # Install cppreference manual.
$ devhelp
