Error in logs: untime error: invalid memory address or nil pointer dereference

[Luigi Maselli]

yarr is fantastic and it works very well, I just got this error in the logs but I didn't noticed any issue.
Maybe because it tried to open a non textual content via full preview

[nkanaev]

fixed in e62906e.
thanks for the report!

[nkanaev]

the error was caused by the readability functionality failing to extract content. minor error, shouldn't affect the application overall.

Thanks!
