Today I wanted to upload something with the program Filezilla 3.28 in Fedora 26 (Kernel 4.14.13-200) and see an error message:

filezilla: symbol lookup error: filezilla: undefined symbol: _ZN2fz6threadC2Ev

I have removed the program and installed, the error message is the same.

Now I have read in the

https://bugzilla.redhat.com

and seen that this a bug in the program. It should be an installing to the version 3.30 but it is still in the testing repositories.
