QFileDialog to select a file returns Permission denied

cerr

Hi,

I need a file dialog to open get the path to a binary.
I've tried:

    PathSet(QFileDialog::getOpenFileName(parent,
        nme_get()+" binary", "/usr/bin", "All Files (*.*)"));

which seems to work only that it prints QInotifyFileSystemWatcherEngine::addPaths: inotify_add_watch failed: Permission denied to stdout when it opens up plus the dialog is unresponsive for a few ~3(?) and the files in /usr/bin/ seem to have finished loadinng - before I actually can interact with the dialog and choose a file. How do I

get rid of the permission error
make the dialog more responsive? There's nothing else n the function that could/would block it nor is there anything else in my application going on in the background. It's just waiting for this file...:

void ScaperDialog::ChooseBin(void) {
    PathSet(QFileDialog::getOpenFileName(parent,
        nme_get()+" binary", "/usr/bin", "All Files (*.*)"));
}

And further to @jsulm, under whatever user you run your Qt app as, what does ls /usr/bin, or even ls -lR /usr/bin give --- any Permission denied?

my "regular" user account, and no, ld /usr/bin & /ls -lR /usr/bin both list the contents just fine

The root of whatever the problem is lies in the

help you/give you any hints. Otherwise I think you'll have to read up on however "Linux inotify user permissions" work....
