Bug ID: 463796
Summary: KIO::copy Segmentation fault
Classification: Frameworks and Libraries
Product: frameworks-kio
Version: 5.101.0
Platform: OpenBSD
OS: OpenBSD
Status: REPORTED
Severity: critical
Priority: NOR
Component: general

Target Milestone: ---
For a long time there has been a really annoying crash in all KDE applications.
For example:
You will just copy/paste a file in dolphin file browser.
“Save as” in Okular - Universal Document Viewer.
I found out it's in FileProtocol::copy / KIO::copy and I wrote a simple test
to reproduce the crash:
```
KIOFileCopy::KIOFileCopy()
{
QList<QUrl> sourceUrl = {
QUrl::fromLocalFile(QLatin1String("/home/rsadowski/src/kio_file_copy/build/bin/fileA.txt"))
};
const QUrl destinationUrl =
QUrl::fromLocalFile(QLatin1String("/home/rsadowski/src/kio_file_copy/build/bin/fileB.txt"));
KIO::CopyJob* job = KIO::copy(sourceUrl, destinationUrl, KIO::DefaultFlags
);
}
```
Debug output:
```

Unfortunately I don't make any progress when debugging and would appreciate any
ideas.
