Bug 349610

I'm observing the same on the latest available version in Fedora 22:

$ rpm -qv kwordquiz
kwordquiz-15.04.0-1.fc22.x86_64

Steps to reproduce:
1. launch kwordquiz
2. Enter "foo" in Column 1
3. Enter "bar" in Column 2
4. Save as into ~/kwordquiz-test

Result: "File is not writable"

Reproducibility: 100%

It's not the filesystem issue:
$ ls -ls ~/kwordquiz-test*
$ ls: cannot access /home/dawid/kwordquiz-test*: No such file or directory
$ echo foo > ~/kwordquiz-test.kvtml
$ ls -ls ~/kwordquiz-test*
4 -rw-rw-r-- 1 dawid dawid 4 paź 31 18:55 /home/dawid/kwordquiz-test.kvtml

However the problem seems to be more generic becuase "parley" is also affected by the same issue and reports: Writing file "Untitled" resulted in an error: File is not writeable.

Versions of qt5 and kf5 related packages (output of: rpm -qa kf5* qt5* | sort  >kf5-qt5-versions.txt)

stracing the kwordquiz during the attempt of saving a file gives the following output:

It looks that there is no single attempt to really create the "/home/dawid/kwordquiz-test.kvtml" file.

I can comfirm this.
The problem is in libkeduvocdocument.

The saveAS()-method of the KEduVocDocument-class creates an QUrl from another url, but it should do it from the QString Path of the local file.
Otherwise it tries to store files like "file:///blah.bla" on the local filesystem.
This usually fails, since the directory "file:" is not existant in the CWD.

 
The patch which works for me is :

DISCLAIMER:
I have _no_ experience in debugging KDE-apps. I am just interested in parley.

It looks like the problem is solved, by cleaning stalefiles:

rm -rf .kde4/data/stalefiles/*
rm -rf .local/share/stalefiles/*

Problem has not been resolved by deleting the listed directories here.

wasn't it fixed here ? https://projects.kde.org/projects/kde/kdeedu/libkeduvocdocument/repository/revisions/adff24a2a7130ac99fa772c1b47fa06aedd01a60

I can confirm the small patch in comment #5 works as advertised (tested with kwordquiz successfully saving now)

fix from bug #356233 works too, but it was committed only to master/ branch

triaging to libkeduvocdocument

Ok, cherry-picked 0cb9b9aea2264fc66d25fb6d93adc32c75dfef97 from master to Applications/15.12 branch, so it will be in Applications 15.12.3 release next month.
