Geany 1.32.
Preferences->General->Miscellaneous: "Project file is stored inside the project base directory" checked. A project is open.
If project base path is absolute, everything works as expected. However, if project base path is `.`, "Generate tags" hangs.
I found that Geany does not hang actually, but waits for `ctags`. However, it indexes *not* the project directory but *current* directory, which is my home directory. My home directory contains many projects, indexing it requires a lot of time.
