Bug ID: 446721
Summary: Figuring out "The file or folder \"\" does not exist"
popup
Product: frameworks-kio
Version: 5.60.0
Platform: Compiled Sources
OS: Linux
Status: REPORTED
Severity: task
Priority: NOR
Component: Open/save dialogs
Assignee: kio-bugs-n...@kde.org
Reporter: rjvber...@gmail.com
CC: kdelibs-b...@kde.org
Target Milestone: ---
SUMMARY
I'm running a utility against 5.60.0 on a machine where I'm blocked on that KF5
version. Everything works fine, but I'm getting a spurious error popup telling
me that "File or folder \"\" does not exist" whenever a custom save dialog is
opened.
I know this is probably considered an ancient version, so I'd just like to get
some suggestions helping me find the source of the problem, i.e. where the code
tries to access a file without name. Or a link to the KIO ticket where this
issue was fixed, if this is indeed a known problem in earlier KIO version(s).
I've tried setting a breakpoint on SlaveBase::error() which seemed like it
should be the place where the corresponding error code is set, but that never
got triggered.
As far as I have been able to determine:
STEPS TO REPRODUCE
1. Open the file save dialog with
```
FileDialog::FileDialog(QDialog *parent, Qt::WindowFlags flags)
: QDialog(parent, flags)
, m_fileWidget(new KFileWidget(QUrl(QStringLiteral("kfiledialog:///foo")),
this))
{
setLayout(new QVBoxLayout);
layout()->addWidget(m_fileWidget);
```
OBSERVED RESULT
The aforementioned error message pops up; after clicking it away I get the
expected file dialog without any signs of trouble.
EXPECTED RESULT
No popup
KDE Frameworks Version: 5.60.0
Qt Version: 5.9.8
ADDITIONAL INFORMATION
I introduce the `kfiledialog:///` QUrl, the original code passed an empty QUrl
which seemed like it could be the source of the problem. It didn't make a
difference.
