The ui__error/warning functions use gtk infobar or statusbar and
pr_* functions use statusbar too. But after perf gtk context
created but those infobar and/or statusbar not yet set up,
calling one of those functions will get a segment fault.
Although current code has no problem, move these setting as early
as possible so that it can prevent the segfault from future change.
