Settings may crash with NumberFormatException if number="" (i.e. after choosing language).

Actual behavior

I opened the app and then i clicked on edit after that i clicked on select which is at the bottom of the right corner. And then in Settings I clicked on output zip file, short text file in zip, long file:Min text Len and then in long text file in zip, options. In all the options i removed all the text and putted numbers. After that I clicked on language and choosed a language. Suddenly the app crashed. And then i tried to open the app again. But everytime it always crashed.

How to reproduce

• First you need to download the app from fdroid and then install it. After that open the app.

• Click on the edit and then on select.

• After that in settings press on the output zip file, short text file in zip, long file:Min text Len. And remove the text and numbers.

• Then click on language and choose anyone. Suddenly the app will crash.

Thans for reporting

the issue is reproducable.

If

• you remove the number value from a number field "long File: Min Text Len"
• and then change the language
• the settings activity is destroyed and then recreated with invalid number value
• ==> crash with number format exception.

In my opinion this is a minor so i will not create a hotfix release.

Will be fixed with the next release 2.0.13.
