[Bug 390288] KIO/KDirModel: Kate crash while trying to save a new file to a Samba share

[Dominik Haumann]

Hi everyone,

given the momentum we currently have in KIO fixes, I would like to raise
attention to the bug below, which may be 10+ years old.

Maybe we have some developers here who can reproduce?

Best regards,
Dominik

Hi Dominik,

yes I can reproduce this issue systematically.

A/ Test case avoiding the bug:

I can create an empty text file in the remote Samba share with Dolphin. Then
open that empty file with Kate, feed it with some text and save it: no
issue.

B/ Test case hitting the bug:

Launch Kate, type in some text, then click Save, navigate to the "Network"
shortcut, then double-clicking "Samba shares": Kate crashes in less than a
second.

By reading the first part of bug #190535, I had the idea to launch Kate from
Konsole. As soon as I click Save (to select a destination folder), this
information displays in Konsole:

kf5.kio.core: Refilling KProtocolInfoFactory cache in the hope to find ""
kf5.kio.core: KSambaShare: Could not find smb.conf!

Each time I navigate to a new local subfolder, I get this information:

kf5.kio.core: Refilling KProtocolInfoFactory cache in the hope to find ""

Then clicking the "Network" shortcut to the left of the Save window:

kf5.kio.core: Refilling KProtocolInfoFactory cache in the hope to find ""

As soon as I double-click "Samba shares" to the right, I get this in
Konsole:

kf5.kio.core: Refilling KProtocolInfoFactory cache in the hope to find ""
kf5.kio.core: Refilling KProtocolInfoFactory cache in the hope to find ""
kf5.kio.core: Refilling KProtocolInfoFactory cache in the hope to find ""
kf5.kio.widgets: Items emitted in directory QUrl("smb://") but that
directory
isn't in KDirModel! Root directory: QUrl("smb:///")
Item: QUrl("smb://workgroup")

Remember my Samba share is hosted on a Linux Mint 18.3 machine. On that
machine, when right-clicking the folder shared with Samba and selecting
option
"Sharing options" (or equivalent English translation), I can notice that
message: "The share name is too long" (or equivalent English translation).
In
my case, the share name is "Partage Mint-land".

I hope this helps. Feel free to ask for more details if needed. And thanks
for
your investigation.
