Hey ..i have the following python code using the PIL Library:import Image,
ImageDraw, ImageFontfrom random import choicedef createCaptcha(): imgtext =
''.join([choice('QWERTZUPASDFGHJKLYXCVBNM') for i in range(5)]) img =
Image.open('captcha_bg.jpg') draw = ImageDraw.Draw(img) font =
ImageFont.truetype('captcha_font.ttf', 50) draw.text((10,10), imgtext, font
= font, fill=(0,0,0)) img.save('captcha.jpg') createCaptcha()Sometimes it
works .. 1 time in a row, or 5 times in a row ..But often i get the following
error:/usr/bin/python -u "/home/julian/Desktop/captcha.py"*** glibc detected
