Tested on Windows, problem does not appear.

Kubuntu 14.04

Interesting - no repro for me in Chrome stable 60. On Ubuntu 14.04 I don't see the %20's appearing in the filenames, and inspecting the HTML the multiple spaces are preserved (i.e. the `li.innerHTML = input.files[i].name` line is preserving the spaces). 

Did you selected both files together?

One by one works fine.

Yes, both files. (Also tried drag/drop - same result.) Hrm, I wonder what's different. 

I tried drag and drop, it works perfectly. I'll try on my other kubuntu 14.04.

My work computer also does it. (same 14.04 KDE)

Is the file dialog from the OS, or chrome provides it?

Did you put more spaces into the file? It is only working if you use more than one space more than once. (don't ask how I found this ;-)

Yes, multiple spaces. (Your repro steps were very clear, but thanks for checking!)

I was wondering about the file dialog; I'm using the cinnamon window manager (as are most Googlers on linux, I think). 

I tried to look for libraries, but chrome is statically linked. Still it opens the KDE File select dialog. 

Is chrome using dbus or similar to open it? Then I can imagine some encoding fun.

Additionally I updated everything related to kde and dbus, nothing changed. Tomorrow I'll boot into a clean kubuntu iso. Let's see what happens.

Additional steps to reproduce:

1) download kubuntu 16.04.2.iso and boot it with virtualbox
2) apt-get update
3) apt-get install chromium-browser

and repeat the original steps.

Since the user agent mentions "Ubuntu Chromium" (and you also mention "(chrome)"), I just want to verify - does it reproduce with Google Chrome?

I reproduced it with Google Chrome 
"Version 60.0.3112.78 (Official Build) (64-bit)"

Hi,

I'll create a video. Please note, that this seems to be a KDE related issue. You are using Ubuntu. My repo is on KUbuntu!

Cheers,

Tamas

The issue seems to be reproducible on OS-Kubuntu and that particular OS doesn't seem to be available with TE-India Team. Hence, adding label TE-NeedsTriageFromMTV for further investigation.

Thanks...!!

Confirming. Seems like an issue with the filesystem chooser and not chrome.
