Description Francis Herne 2016-05-03 09:25:46 UTC
When opening files containing one or more double-quote characters:
e.g. «Testfile("Word").txt» or «Test\"word.txt»
via the file selector, KDevelop crashes.

Opening such a file by itself via the file selector is impossible, when clicking on the 'Open' button nothing happens. When ctrl-clicking or dragging to select multiple files, one or more of which have a double-quote character in their name, the result below occurs.

If doing this in a session, all future attempts to load that session will crash KDevelop in the same way.  The session must be deleted and recreated.

Opening such a file via the Filesystem pane, or from a CLI argument, is successful.

KATE also fails to open such files, either reporting that parts of the filename aren't files or opening the wrong file, but doesn't crash.

Gwenview and other KDE applications fail to open such files, but also don't crash.

Hmm, this bug probably shouldn't be here. But I typed it now. :P

Reproducible: Always

Steps to Reproduce:
1. Create a file named 'Test-"File".txt'.
2. In the file selector, attempt to open that file.
 - Clicking 'Open' will have no effect.
3. In the file selector, attempt to open that file along with at least one other file.
 - KDevelop will crash.
4. Restart KDevelop using the same session.
 - KDevelop will crash again.

Actual Results:  
ASSERT: "!inputUrl.fileName().isEmpty()" in file /home/flh/projects/src/kdevplatform/shell/documentcontroller.cpp, line 226

On another occasion I got:
kdevplatform.language: INVALID URL ENCOUNTERED: "/home/flh/ " QUrl("file:///home/flh/")
ASSERT: "isValidURL(url)" in file /home/flh/projects/src/kdevplatform/language/backgroundparser/backgroundparser.cpp, line 534

Comment 1 Francis Herne 2016-05-03 09:30:43 UTC
Correction: Steps to reproduce are true for a file with one doublequote, not two as shown.

In case of two, opening a single file, KDevelop will open (create) a file with the fragment of the filename between the quotes.

When opening multiple files, KDevelop may open/create files with the end fragments instead.

Everything is wrong, anyway.
Comment 2 Francis Herne 2016-05-03 09:53:15 UTC
I suppose this is the right bug, unfixed for seven years: https://bugs.kde.org/show_bug.cgi?id=185433

Opening different files to the one requested seems seriously wrong to me. :-/
