#88 Crash when drag&dropping files onto Xfce desktop

[Haddayn]

When I try to drag & drop a file from an archvive onto Xfce desktop, xarchiver crashes.
When launched from the terminal, I see

segmentation fault (core dumped) xarchiver zip.zip

It works normally with a file manager.

Also when drag over chrome window

I have the same problem with xarchiver

xarchiver --version
xarchiver 0.5.4

dmesg output:

Installing xarchiver-dbg only changed the first 2 backtraces. I could try to install other debug infos, if this helps.

I have the same problem. I digged a little into source code and here is what I've found.

When user drag&drops a file onto XFCE desktop, the following steps happen:

1) window.c: a call to the gdk_property_get (line 1697) writes "xds.txt" to _destination variable. When I drop a file onto a "normal" directory in Thunar or similar file manager, this variable contains a "normal" file URI like "file:///home/user/pictures/xds.txt".

2) window.c: a call to g_filename_from_uri (line 1715) returns NULL, which is assigned to the desination (w/o underscore at the beginning of the name) variable. According to glib manuals, NULL result indicates error; indeed, when I modified the code to display the error text, g_filename_from_uri returned this message:

The URI 'xds.txt' is not an absolute URI using the "file" scheme

3) this variable is then passed as an argument to the function xa_remove_level_from_path from string_utils.c. Inside this function at line 151 there is a call to the strlen function with path argument equal to NULL, which leads to segmentation fault.

I would love to fix this myself, but have zero experience working with glib and gtk.

[shinonome]

I think this should fix it. The patch is for the latest version (0.5.4).

[Yanpas]

The existance of patch is cool, but will it be applied to project? Isn't the xarchiever forsaken?

[Giuseppe Torelli]

Hey guys, the project is not forsaken and I'm still alive. Would you please collect all the latest patches (not the jumbo one) so I can apply one after one and release a fixed version?

[shinonome]

Here is all I have found for version 0.5.4. I tried to apply all patches and got two problems:
1) no-xfce.patch fails to apply.
2) xarchiver-gtk3-port.patch breaks the build.
Without them the program builds and runs fine.

[b2f9h203]

Because there is still no update, I took the time to install the patches.
Firstly: they work :) thank you
Secondly: Sadly it doesn't work perfect. I can't extract multiple files per drag&drop, only single files.

[Giuseppe Torelli]

I knew I shouldn't have applid the patch... ;) by the way, the effort is highly appreciated :)
