Can someone confirm?

Hello, all.

My kdevelop 5.5.0 in updated FC30 behaves strange: when I click
in the build tab the error line from the compilation I expect
kdevelop to open the erroneous source file at the erroneous
line.

Instead of this, it opens a new tab named after erroneous source
file as if this is empty file.

Even if there is already this file in some tab opened, kdevelop
still opens this empty tab named the same name.

My compiler is ordinary gcc/g++, files have normal permissions.
I don't know what to check more...

Anyone can confirm this behavior?

Thanks.
