[Interest] QPixmap on Linux

Hi.
I found that sometimes QPixmap can't load correct image file.
The next lines
const QPixmap p( path );
qDebug() << "is pixmap null" << p.isNull();
produces from time to time
Konsole output
is pixmap null true
What it can be? File exists, all is ok with image.
I have to say that I do monitoring of the folder for new image files
with QFileSystemWatcher.
On directoryChanged(QString) I use QDir::entryInfoList() and check for
modifications in directory. If so I emit signals fileAdded(QString) or
fileRemoved(QString). In slot connected to fileAdded(QString) I'm
loading QPixmap as I said before. But loading may fail.
Can it be problem with file system? May be file can't be opened from
time to time?
I'm on Linux. File system is encrypted.
