#1561 open package documentation can cause crash

[Zash]

If the right click command "Open package documentation (<package>)" fails, i.e. does not find the documentation file, TexStudio crashes (unrecoverable).
TeXStudio 2.10.4
Windows 10
MikTeX 2.9</package>

please give an step-by-step example before we need to start guessing what exactly you did...

Ok, after further testing the crash seems to be only reproducible for the second time you do the steps below:

Preperation

1. Create a new .tex document
2. Add a package, which does not have a documentation file available in the installed LaTeX distribution (for me, it is for e.g. the package fontenc in MikTeX) - see example below.

Reproduce crash

1. Rightclick on the <package> name and choose "Open package documentation (<package>)"</package></package>
2. TeXStudio shows an empty and the error massage "Documentation for <package> could not be found"</package>
3. Close the error massages.
4. Repeat steps 1-3

Now TeXStudio does not respond anymore (freezes) and has to be killed

Document example:

\documentclass{article}
\usepackage[utf8]{inputenc}
\usepackage[T1]{fontenc} % Right click on fontenc
\begin{document}
test
\end{document}

seems to work fine on linux.
Tim ?

@Zash: Is Options -> Advanced Editor -> Special Options -> Show help on commands in internal pdf viewer (texdoc) enabled or disabled?

[Zash]

Disabled, external viewer is PDF-XChange Editor.
