hatch freezes inkscape with empty document

[polycopter]

seems like a timeout or test for serial connection might be missing?

The WCB Hatch Fill extension does not attempt to communicate with the serial port in any sense. It is purely a graphical effect, and does not have any code that can create or detect a serial connection.

If it is crashing for you, I would be very surprised (and utterly stumped) if there is any correlation to whether the WCB is plugged in.

Can you please say:

• What operating system version you are using
• What Inkscape version you are using
• Whether the freeze is reproducibly related to whether or not the bot is plugged in.

my bad. I think the issue was not the bot being unattached, it was the document being empty. some kind of "sanity check" may be missing. obviously not a high priority issue, why would anyone try to hatch fill a blank document? unless, like me, they just want to see what happens. I am running Ubuntu 13.?? (I forget, and don't know how to check, but I think it's a higher # than 10 in the last 2 digits), Inkscape Help->About reports 0.48. Steps to reproduce: launch Inkscape (get a default blank document), select Extensions->WatercolorBot->hatch fill... wait a little while (nothing happens, apparently)... then click Cancel; Inkscape is frozen. It may be frozen already, before you click Cancel, but I haven't waited a long time to see if it finishes, or times out, or something, and becomes responsive again, before clicking Cancel. I have waited a long time after clicking Cancel, though. Process monitor shows Python taking up a steady 12% of the CPU.
